FordTechMakuloco are there any videos on PCV lines replacement on older 2 valve 5.4 motors? I’m having a tough time with that elbow hose at the base of the rear intake manifold, it’s an expedition so the firewall makes it extremely tough to get back there and release hose clamp to pull off? Do you guys pull throttle body off to gain more access? Thanks bud.

@jetjoey19 5 лет назад

What if the LTFTs dont move? They stay at 1.00 percent and STFTs are at .63 and bank 1 sensor 1 doesnt fluctuate lile bank 2 senaor 1. Its giving me a P2195 code. I "cleaned" the pcv and check engine light comes on much quicker than before

@ArthurFleck-tx9di 16 дней назад

@xcataclysmx I don't know if the man here himself knows or has ran into this... After days and days There is a very big difference in those spark plug numbers. I will say I discovered and I will also say that in the back of the intake where it meets the heads. We're leaking ever, so slightly. You could not notice a misfire, didn't really have any symptoms that you would think? Nothing like the brake cleaner trick. Nothing like that would work. Nothing made sense. Put a smoke machine on it. Nothing and then I got the idea well. Let's pressurize the smoke a little bit and then the smoke started rolling out of the back of the intake gaskets on both sides. It was slightly leaking and that was causing so many problems

@williamabaker12 3 года назад

Definitely check the foam on the air filter box. I have a 2005 expedition 5.4 that wasn't pulling any codes (at least not to the point of tripping the check engine light), but I was getting atrocious gas mileage, as well as a drastic issue with power at times. When I would floor it, I would get almost bursts of power between bogged down acceleration. I also had the obnoxious diesel sound once warm at idle. I found that issue, cleaned off all old foam, and replaced with new padding. It solved all my issues, including (somehow) quieting down the engine.

Perfect Video and Perfect Timing! Bruddah as always - You and Your Videos Rock !! Got a couple important questions for you. 1. How reliable are the "Re-man'd sensors"? And... 2. What companies would you recommend if we can't buy from OEM? 3. Which companies have you steered away from? I have yet to hear any good things about Dorman electronics and of course their "exact fit parts" are already #1 on the Top 10 Don't Buy charts - unless you really, really have too. Even then -- "Buyer Beware". The wife's 2007 toyota Camry has been giving us issues lately. Her XLT Camry was bought new in summer of 2007 and has been a trouble free car from day one. Now at over 100,000 miles it's asking for some normal and expected detailed, in-depth and attentive TLC. And she'll get it. Great Car. Last week I was getting the same codes you spoke of in the video wrt the fuel trims and DTC's. Wife came home from work saying the "Check Engine is On". Using your past videos as a guide and my scan tool combined with my very limited skill sets - I was able to fix all of the issues by simply cleaning the MAF, the throttle plate and the K&N flat air filter. Bruddah - I can say this - All is well in the islands. Happy Wife - Happy life and it's real time proof to the wife that (pounding my chest like Hercules) "Man needs to buy more tools!!" -- "Honey, buying that $400 scan tool just saved us a lot of money" and "this tool just paid for itself!" (cough - cough - ah - emm, honest it does ;)) Once Again Your Videos let me fix it right and saved us a boatload of money by not having to spend on things I didn't need to buy. Not to mention that I am able to better Interpret, Understand, and Utilize my scan tool. I was really worried that I'd have to buy a new MAF and/or TBS. That would of easily cost me over $500. Toyota over here wants $198 for the MAF and a new Throttle Body (sensor included) is over $300. The TPS sensor isn't sold separately over here. I went to a friend who works at a Toyota dealership in the parts department and said the same thing "sorry bruddah - You have to buy the whole Throttle Body assembly". They said it's because of the TPS and Body design. I Say - I smell a wolf in the hen house as I cough "Rip Off" out loud. Any Howz -- Thanks Again Bruddah!!

I went through H*LL trying to fix my lean codes on my 2005 3V 5.4L F-150...Isolated every vacuum line, pulled the manifold to check for cracks, replaced MAF, replaced fuel pump and then Fuel Pressure Sensor. Went to 2 Ford dealerships and a diagnostic shop. Last shop says everything checks out and I had to think outside the box. They even replaced the computer at no charge when it didn't fix the problem.. I had a scanner that showed the fuel trims and knew they were off. Also took into account the problems with the 05 injectors. I went one size up and replaced ALL the injectors. That solved the problem. Trims went to the Rich side but within spec. Hope I'm not just masking a problem. Been 2 years, no problem

@kevintucker3354 4 года назад

The 2V engines also tend to show bank 2 lean first. I’m thinking it’s the intake manifold runner design. The way the air moves through the manifold.

@bobjohnson8206 5 лет назад

Your videos are really outstanding. i never paid any attention to the bottom of the air filter as you described in your video so I inspected mine. Guess what mine was all falling apart as you have shown in the video so I order the tray seal. Upon receiving the seal the exact measurement of the seal width is 1 1/4 inches and the old foam was 1 inch so it had to be trimmed off to the exact width as needed. However the seal really sticks onto the housing just wanted to give a heads up so others will know what to expect. Although I don't have any error codes yet just trying to eliminate them before they occur. I am a firm believer of preventive maintenance. Can you tell us what the part numbers for the two hoses you described in your video in reference to the vapor feed hose and the brake booster hose to the bottom of the intake. I would like to replace both of them now before I have a problem. Many thanks, IMHO your the best videos out there.

@Hollywood4Fun 2 года назад

I have the same year truck with the same motor. Today when leaving the hardware store it started making a strange intermittent clunking noise coming from either the engine or the front wheel area. I thought for sure it was something serious with the engine. The check engine light came on and code 174 and 171 were discovered later. I decided to try to drive it home 6 miles on the highway. Once I got up past 25 miles an hour there was no more clunking and the engine seemed to run fine. As soon as I got near my house and reduced speed to around 20 miles an hour the clunking resumed. It almost sounded like the four-wheel drive was attempting to engage. I got it to the garage and clean the mass air flow sensor and took it for a test drive. The clunking remained present at low speeds. When I purchased the truck which has 220,000 miles on it there was a check engine light on but after changing the oil and adding some Lucas it went away. The previous owner thought the vehicle jumped time but it ran fine for me although the codes at the time did seem to indicate an issue with the cam phasers or the timing chain. I'm wondering if the timing chain or the slack adjusters have finally worn too far? Oddly however at highway speeds it ran fine. It wasn't just a rough idle at lower speeds it was definitely clunking intermittently. I'm going to further check the vacuum lines but it sounds mechanical. Any advice?

@monroepede1 4 года назад

Would have been cool to see the test drive with the new MAF sensor. That way we could see the fuel trims at higher RPM's. Great video regardless. Very informative and helpful. Checked my filter door seal and it was completely gone. Giant gap for air to enter housing. Seams like the filter seal would stop that from vortexing the MAF sensor area, but I trust your expertise over mine. I think I will try duck tape first, if that works I'll be looking for that air filter door seal. If you know where to get one, let me know. The vortex in the air filter housing was good info. Are there other seals on that housing I should check? Can't tell unless I take it all apart. Didn't want to fix what isn't broken, even though I do that sometimes anyways. Great info, thanks for the tip lesson.

On my 2006 F150 5.5 3v I'm getting P0174, P0059 and P2197. Truck runs great warm, but rough at cold idle. Foam trim on air cleaner tray was gone so I replaced it but didn't do anything to clear memory yet. I've used oil k&n air filter for past few years and see oily film on outside of MAF. All vacuum lines appear sound on initial inspection, but not tested. Previously had IWE fail so I plugged the vacuum line to it for a couple months, but no codes until 10 months after vacuum to IWE reconnected. Any thoughts on cause of these 3 codes? Thanks!

I'm throwing a code p2195 on my 2006 f150 5.4 3v... about a month ago, I took it in to advantage ford in Fremont ohio and had them replace my cam phasers and oil pump. they said that I would need a catalytic converter on the driver side here sometime soon. would that cause the code? I cleaned the MAF sensor, air intake and throttle body. I will be looking into changing a couple of the hoses mentioned in this video.. the reason I'm asking is because all the research I've done, it's usually more than just a single code for the vacuum leaks. please let me know at your earliest convenience. thanks

Hey guys,quick question this pertains to the 3.5 duratec v6 so obviously a different engine but this guy knows his stuff so I'd thought I'd ask,so I've heard the 3.5 can be prone to water pump failure ,and this can/will destroy the engine if this issue is severe enough my question is was this issue resolved?Have a 17 explorer duratec was hoping to keep it for a very long time,and I heard they reworked some mechanical components with the 16 refresh so was wondering if that issue was one of them.

How long of a test drive is needed to relearn the baro frequency? Any special procedure like WOT necessary to relearn?

Hey this has nothing to do with a LEAN code but i really need help on something for my 98 Ford EX. Getting the flashing OD light every now and then. Code reader saying Range sensor #3 shorted or low voltage. I checked with live data and all the range sensors say CLOSED except for #3 which says 0V. I thought the range sensor was all one piece. Any ideas?

How about information about the PCV valves on these engines, kind of a different setup than the 2 valves. I have a 4.6 3 valve and apparently the PCV valve is part of the valve cover and can only be replaced by replacing the cover on the 3valve engines. Are they built like regular PCV valves, servicable etc. I have a small vacuum leak(I think) at idle that is pushing up long term fuel trims and wonder if the PCV valve in my 3 valve could be the culprit. Any way to test them, and how do they tend to fail? Thanks.

I also have the 5.4L 3v and I checked my seal on my air filter door, after watching this video, and my seal is completely gone. What do you recommend to fix the door seal? I imagine they don't sell that seal at the auto parts store. Do we make one? If so, what material is best to use for the new seal? What thickness? Do you think this vortex could cause severe lean condition and rough idle and driveability issues?

Do you have any videos of you replacing the remote oil filter lines on a 98 f150 4.6?

I have a mystery p0174 on my 07 explorer 4.6 3v. I changed plugs, maf, upstream 02's, fuel filter. Still got the code. I then changed fuel injectors. Mostly fixed the issue, like 95%. Still get the odd p0174 when full hot after a long trip then restart while hot. Do you think pvc sticking open? Is pcv built into the valve cover?

Do the Newer MAF update the Baro the same way the Old one's Did ? You had to operate at WOT a few times before Baro would update. If I remember Correctly PCM only Looked at Baro at Start Up and a WOT event. If no WOT-- PCM operated at Baro reading for entire time engine was running. Baro was Altitude Compension Input to PCM. Is that still True ?

When you say disconnect the battery do you actually mean to disconnect both positive and negative cables for ten minutes or so? Or if we don't have a scan tool that can reset KAM, is doing a KAM reset using your KAM reset procedure enough?

@FordTechMakuloco 7 лет назад

Just pulling the negative is good enough. Much easier for me to do a KAM reset with the scan tool but both accomplish the same task.
