1A Auto Parts Great videos as always! Could you please do this type of video for the 1998-2003 Toyota Sienna minivan? That would be awesome as there are not many videos on RU-vid regarding the Generation 1 Toyota Siennas.
Can replacing the intake, spark plugs & boots, and injector O-rings somehow make the car more sluggish than before? Does the motor need to reprogram itself, or must that be done manually? Otherwise it starts better and idles smoothly. It just doesn't have the lemons it had before. Thank you for any advice offered.
1970s: trouble with Iran, Cafe legislation makes trouble for our domestically made vehicles so in 1978 Ford designs the Panther frame and has them built in Canada to bypass the cafe restrictions producing the Panther platform vehicles as an import along with the mustang so that we can continue to have real cars. Fast forward to 2012: Obama passes legislation making it illegal for the Crown Victoria's to be sold in our country unless they get an upgraded computer system and so every 2012 Crown Victoria was sent to Iran. Coincidence? I think not. There's obviously a concerted effort against us. ☠️
They'll stop making cars once they start lasting too long and ford can be making more money on shittier cars cause ppl are sheep that just has to have a new car. Planned obsolescence 😫😫
Ford's hands were tied, Legislation made it impossible to sell them here. Ford was trying their best by making them in Canada, but eventually time ran out.
Mass air flow sensor: clean it if dirty; if you need to replace it use a Motorcraft MAF sensor only. Spark plugs, replace them and torque them to 25 lbs/ft and use no anti seize on them. The Motorcraft plugs do not require the use of anti seize. PCV valve, that is a simple easy change and cheap. Intake manifold, no need to replace if you have the 2005 and newer aluminum coolant plenum. If you have to replace the manifold use the Ford part only and it will come with brand new gaskets. Torque to spec and be sure to follow the correct torque sequence. Also the oil filter housing gasket tends to leak on high mileage cars, which results in both an oil and coolant leak. Replace the gasket with a FelPro gasket, cost: about $9. Overall these are very good reliable cars and can really take a beating.
You are so right about following the proper sequence and correct torque on any intake or head gasket change. Some people don't understand how crucial this part of reassembly is.
I have the Grand Marquis, excellent vehicle! When doing the intake manifold, go with the Ford Racing Performance intake. It will increase airflow in the higher RPM's allowing the 4.6 ltr to breathe much better. Dyno tuning will show an increase of nearly 50 hp at the top end, and allow the engine to rev another 800 rpm's. BTW.....it was only $238 at the time, so less than $300 and four hours later, I have a pretty damned quick Mercury!
Here's some real information on the spark plug issues in these cars, and those alike with the same engine. The spark plugs blow out because of human error, not a manufacturer defect. Fords original torque spec was way too low, this caused many people to experience this blow out. Ford soon after updated the torque spec on the plugs, and it eliminated the issue. If you had a spark plug blow out in a 4.6 2v, it was either your mechanic or you improperly torquing the plugs. Fords original torque spec was around 10 pound feet. Now it is commonly accepted to do 25-30 pound feet.
This can also be caused by the engine overheating and then softening the aluminum just enough. Probably also was over torqued at some point. Happened after 2-3 months of having the car. Overheated and within a week it popped.
That's part of the problem. Thread count in the head in 2003 and older 4.6L was too low. Ford doubled the thread count in 2004 which gave better blow out resistance.
i still see cops using the crown Vic's even after there discontinued, i asked one of the officers how many miles are on it, he said 426,000 miles and still patrolling the streets.
@@nickr3441 I've owned 6 panthers, 4 of them with the 4.6. My 95 TC had 465k on the clock when I junked it due to a blown head gasket. would have fixed it if the body wasn't rusting off and smashed up from being totaled by insurance twice. just wasn'[t worth the $200 in parts to keep it alive. Original engine, original 4r70w trans. I did have to replace the tail housing gasket at about 300k miles. as a fluke the gasket between the main and tail housing blew out. took about half an hour to swap out and put another 165k on the clock. Only gave it a Mobil 1 oil change every 8-10k miles and other parts as needed. no serious mechanical issues, just a body falling apart. It's replacement was an 05 TC that has 300k on it now with no issues. have an 03 GM with about 260k, had a bad intake, which is common enough on these at about 230k. most recent daily driver is another 05 TC that has 230k on it now. The 4.6 is a beast that lasts forever as long as you don't overheat it and change the oil before it turns to paste and the 4r70w is bullet proof. And I'm not easy on my engines or trans' Been through 3 5.0's in my 87 mustang and 7, yes, seven, AOD transmissions in the 4 years I drove the mustang.
As a retired mechanic (27yrs), let me say that 1A Auto puts out some very informative videos. Everything you mention here is correct, but I just want to clarify one thing. The spark plug issue. If you own a 4.6 with the 2 VALVE head you shouldn't have any blown spark plugs (assuming they were installed properly). If you own the 3 valve or 4 valve head, and especially the V10, you probably will have plug issues. These heads were engineered wrong from the factory, simply a bad design! I own a 03 Mustang GT and a Lincoln TC. Both with the 2 valve 4.6. Each have over 100k+ on them, and have had no plug problems. Thats why these were so popular with the police agencies and taxi cab fleets. They regularly ran 300k+ on these vehicles! Hope this helps. Keep putting out the great vids 1A auto.

2 more common problems fuel level sensor and the cluster going out in 05+ vics. Luckily changing my cluster out fixed both problems and I didn't have to mess with the fuel pump.
Something I’d like to add about the intake manifold leaking is that if you let it go for too long it can leak into your spark plug holes, which is a whole mess to clean out and could get into the combustion chamber. This happened to me because there was no easily visible evidence of a leak anywhere else on top of the engine until I went to change the spark plugs and set eyes on a nasty surprise.
All Ford had to do was update the looks a little, upgrade the interior, put the Coyote v8 in it and put one of the 10 speed transmissions and called it a day it would've been fantastic stupid of Ford to stop making them
Great video. Regarding spark plugs, motors up around late 2003 or early 2004 have half the head threads of later motors. Best to get a 2004 or later which were redesigned to resist spark plug ejection better. Regarding intake manifold, there are two versions of heads. 1998-2002 are NPI low air flow heads and 2003 and later are Performance Improved PI heads. Each requires different version of intake. For 2003 and later motors, get the Ford OEM with separate gaskets. OEM has better air flow than Dorman. Plus the Dorman has gasket seals built into the manifold. That is one reason why Dorman is cheaper.
Lol! The blend door actuator! 2 Crown Vics so far, both had this happen. My last Crown Vic I had to deal with the intake manifold (at 220k miles). The one I have now, the prior owner replaced it. Still my favorite car. Last forever if you take care of them.
With basic scheduled maintenance, these 4.6L 2V motors are really bullet proof. To grenade one, you really need to be a special kind of someone. The "High Flow" oiled air filters really screw up the MAF sensor. Just say NO to the aftermarket "CAI" systems which are really just "Hot Air Intake" systems.
@@rcrhinehart66 I used KNN on my Grand Marquis and it kept messing up the MAF sensor. I now use WIX filters and they're just as good as or better than KNN. Watch this vid, it's very informative. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-sJ3L-E-ufYo.html
So you're calling the final generation of Crown Victoria the second generation? You all realize the Crown Victoria nameplate came out in the 50s right? I remember my first Crown Vic. It was a 1985 LTD. Fully loaded. So this would be a -1 generation? Crown Vics in the 80s were what, beta models? How about the models from the 70s?
Hell yeah keep real American steel alive! Up here in Canada I picked up a beauty forest green "03 Grand Marquis in mint condition for $1800 bucks. Total steal deal. Been driving it for over two years, 240 000 kilometers and going strong!
I have a 2000 Mercury Grand Marquis w over 200k miles on it & has been more reliable than my 05 GT & 07 GT LOL I am looking for an 08 or newer Ford Crown Vic...they are just very reliable, cheap, easy to work on, & there’s a lot of parts out there for them.
Good video. I have an '01 GMQ HPP - I bought it in 2014 with 44K miles and now has about 120K. I've done the blend-door actuator (not fun), intake manifold, rear air springs and compressor (went with heavy-duty airbags) for major repairs. I used Power Stop brakes for replacement and they are a huge improvement. Now I have a battery-drain issue that I'm trying to figure out. Other than that, it's been a very reliable car.
I have a 2008 Crown Vic that was assigned to me by my State Agency. Two more common issues are the driver’s front door window regulator and the wiper motor. Both items have been replaced twice in the 5 years I’ve been driving it. I haven’t any idea how many times those two items, or the items you discussed, have been replaced between 2008-2015. I’ve seen the same two problems on Crown Vics other Officers drove. I’d still do all I can to keep driving this old Police car before I get anything newer, unless it’s a newer Crown Vic before Ford stopped making them.
I have 05 Towncar. I can go in reverse no problem but all forward gear won’t work until it idles for about 30 mins and when it finally goes, it jerks really hard. When I stop I have to tap the pedal when I release the brake for it to go and it still jerks. Help!!!
@@1AAuto I have a 97 Grand Marquis it shuts off while its running and then starts back up they replaced the intake battery alternator thermostat relays fuel pump filter and it's still doing it any ideas on what it might be??
2010 Grand Marque I love this vehicle. While driving all of a sudden my vehicle stalls. Several days of stalling in the shop she goes. Must be a fuel problem, change the fuel sensor and fuel pump. Runs fine for a week back in the shop we go again same problem. Change the computer, a few weeks later back to the shop once again I’m told it’s the radiator fan regulator and fan unit change that. I’m well over &1,500 parts and labor. Finally I gave in and brought it to the dealership $149 for a diagnostic check after a week in the shop they finally got a code saying it was the mass air flow sensor $70 part. Been running great ever since
Merc Grand Marquis owner here! So far i’ve had to do a blend door actuator for the auto climate controls and also redo the o-rings inside the climate control panel. the blend door sucked but was manageable for me. whole dashboard and even heater core had to come out. yes there are hackier ways to do it but i’d rather take the couple extra steps and do it right than modify stuff to make it work. also, yes weak power. i cleaned MAF but didn’t help too much. no codes. i think maybe manifold. haven’t decided which yet but haven’t found anyone to properly diagnose. crap starting on wet and rainy days in certain conditions or otherwise stalls out just after startup. runs fine when computer decides to compensate but won’t throw codes. just slaggy acceleration but otherwise has decent torque.
I've never had any spark plugs come out of any of my vics....I own a security company and we've had 16 vics so far....not 1 ever had that happen. Mass air flow went out on just 1. And none had any other of these "common" issues ever...
One thing he did not mention, and it’s unavoidable it will happen no Crown Victoria is immune from it. The exhaust manifold sort of the same deal with the spark plugs the bolt or bolts will break from backing out, or the exhaust manifold will crack. If you get a Crown Victoria especially anything over 150,000 Miles do yourself a solid and go ahead and replace the bolts it will 9/10 happen before it hits 200,000 mile mark. Might as well go ahead and replace the exhaust manifold too.
I guess the intake manifold issue is just a case by case basis. I had a 99 town car and an 03 grand marquis and neither had that intake manifold crack or leak.
Great job and the comments very informative also. My 96 T Bird had the 4.6 and someone on you tube had a vid on intake replacement,, key point here is I did not undo most of the upper parts , if i remember pulling the injectors and a few other things and left the harness etc all together , then the intake just comes forward a bit and lifted from the front with the new one sliding under all the wiring and hoses. pretty easy as I was used to working on 302 motors etc which were very simple . like to have another if i could find a clean one.
I had a hard starting or long cranking problem only in the mornings. First thought was the fuel pump losing pressure overnight because once the car was driven it started fine the rest of the day. Long story short, it was the crank angle sensor going bad. Now I have the drivers window that has too much movement when going up. I took the door panel off but couldn't see where I would adjust out the play in the window regulator.
Just had the intake replaced on my 02 Crown Vic. Now the engine has an intermittant miss. I'm planning on going through and disconnecting and reconnecting all the fuel injectors first. Next step will be to check my sparkplugs and coils which I replaced about two years ago. Probably a good Idea to check the torque on my spark plugs. I do need to get the valve cover gaskets done. I'm a shade tree mechanic, but right now as an "essential" employee, I can't get the time off to do my own mechanicing any more. Heater core and intake cost me $2000.00, but I need the car and with interest rates the way they are, I'm not buying another car.
@@zocc4270 nope...no time and my Excursion got wrecked, sooo waiting on repairs for the Excursion. I have a Volvo c30,buttt...the pcv system is messed up, Volvo dealer says fix is less than 1k. When it rains it pours. I work too much lol
Check the driver side plugs for coolant in the plug well. If so, you likely have a leaking intake that needs replacing. Aftermarket replacement is relatively cheap at just over $100, but it's a bit of work to replace.
Hi i own a 2004 ford crown vic and i am having a problem with it the problem is that he starts perfect but sometimes it doesn't starts at all but if i let it stand for 1 hour or so it starts again what could be the problem? I did change starter and selenoid and other pieces too but the problem is still persistent.
Another common problem on the 06 and up is the odometer fading out or loss of power to the cluster usually caused by bad soldiers on the board of the cluster. Im currently having this issue
I got a 04 grand marquis. I will be in a parking lot and it won’t start. When it does crank I have to haul ass home or it will die. Then I will start it up after that and the battery light will be of and it will act fine. Any ideas?
I used to have a Gran Marquis and under moderate load when shifting from 3rd to 4th it would also shake for a couple seconds before finally shifting. Under light load and heavy load it would shift fine though
2007 was last year for civilian purchase. 2008 and up were fleet vehicles. All 1998 to 2012 Crown Victorias were manufactured in Canada. 2011 was the last year for the car except for a limited number of 2012 models that were ONLY exported to Saudi Arabia.
@@1AAuto There are no 2012 models!! All the entire history is east to find from multiple sources, Last car built was made for a person in the middle east and was built on sept 15th 2011 en.wikipedia.org/wiki/Ford_Crown_Victoria_Police_Interceptor
The only legit things are the spark plugs threads which is a big deal and the intake which is a big deal but not as much as the head. The other shit is simple and happens with any other car on the planet.
It’s ugliest cars ever made , it’s like a boat there is no stability, suspension is zero only good engine even that engine plastic intake manifold is crappy but they upgraded on later models anyway it’s a boat not a car for daily use you can’t use it inside town crowded city you’ll get a headache just finding a park for this boat 😂😂😂😂 even it’s fuel sucker in city
Thanks for the entertaining video! How do i find a updated intake manifold ( non flat air flow, with modern higher air tubes in mold ) if you know what I mean! and do I still need to use Felpro Gaskets etc. on the intake even if It has the rubber rings with it? Do I use the gasket set in place of the rings, or both?
Just picked up 4 P7B 2010/2011 crown vic's at auction. 2 had bad intake manifolds, 1 bad fuel pump, ALL had warped front rotors :/ only 1 bad window regulator. Thankfully Amazon and my autozone commercial account saved my ass
IDK why u call it Gen 2 They started calling her the Crown Victoria in 1980 after they made the LTD into a shoebox. So.. this should actually be Gen 3. Gen 1 1980 to 1987. Gen 2 1988 to 1997. Then Gen 3 1998 to 2011. Yeah, everyone forgets the middle one where they made her a bit wider and longer, but still boxy as heck tho.
I never like the Ltd it's was a big copycat like box caprice it's ugly to me we skip over it because it shouldn't have been made in the first place chevy pulled it off with the box caprice ford crown vic are the bubble I got my eye on a 2001 vic
On #2: If a plug pops out unplug the fuel injector so fuel isn't sent to that cylinder. That should get you to the auto machine shop to get a threaded insert installed. Use antiseize on your plugs.
We were absolutely in love with our 2000 Lincoln Town Car Cartier until the plastic intake manifold cracked all the way across the front spraying all the engine coolant out. We had my 90 year old mother with us and we were broke down on the side of the road. The love affair with this car is over. Who ever the genius is that engineered a plastic intake should have to fix one of their mistakes and then be given a cigarette, a blindfold and their last rites.
