FACTORY FRESH / FOXBODY BASE IDLE RESET 2.0 / FIX THAT CRAPPY IDLE! 

You should do a video where you take Andrew’s car away when he’s working; and replace the headlights.🔥🔥🙏🏻👌🏻👏🏻

Ty Brewt. You always do stay on the basics of keeping these cars running right and you're all about it. You are certainly given me the ability to face any issues upcoming I appreciate you man

EEC3. The dealer had a diagnostic machine called the SBDS. It was the size of an arcade game, like the one you put quarters in. The veteran taught me exactly the same things, back in the late 90's, a DVOM, and dial back timing light. .51 to .99 was acceptable tps voltage. Occasionally a dead spot in egr valve position sensor would cause an errant high idle too, we would nick a little off the sensor pintle on the grinder and let it relearn.

Such classic knowledge that needs to be revisited often. Good Job Brew.

Thank you for actually telling the ECU acceptable TPS spread.

When doing a base idle reset you really need to unplug the tps, iac and spout connector. Set the idle screw to where the engine is barely idling around 400-500 rpm. Then plug everything back in. The reason you need to unplug everything is because all of those things will try to correct the idle as you turn the idle screw off they are plugged in.

You're a brave man. Going to pick up the BLACK WIDOW MOBILE in the heart of SPIDER COUNTRY!!!!!

This video is a great example of why I’m subscribed. I love your videos, but you sir are a well of knowledge for the Fox Body community, and I would love to see more vids like this. You have an excellent way of explaining things.

Nice little covert operation good video I've gone back to your older ones that helped me so much

By far one of the best DIY for Foxbody owners and so knowledgeable

Very well done video. This is how I’ve fought my idle for a while now. I’ve got it exactly where I want it

This was some classic Brew2L stuff plus it was on my favorite car on the channel. Great stuff!

Excellent distribution of knowledge. The earlier Fox's were a nightmare to get the idle to act right. I've got about 1,300$ in tune now and my car (heavily modified) will sometimes fall on it's face when I'm on the highway and take an exit. I downshift and use the brakes. It dies here quite often. I'll try your wisdom and I hope it acts right!

I just got my first Fox back in July (an '89 GT vert). The way Andrew's idles when you first adjusted it on the throttle body at 2:26 is exactly what mine does right now, especially during coldstarts (and that's AFTER it spends about two minutes bucking like it wants to shut off). All of this information is really helpful!

Perfect explanation, very thorough. Thank you for the extra advice when running a cam, helps a lot. 👍

Your first video helped me out so much, and man that couldn't be further from the truth when it comes to cammed cars. Mine has the TFS 1 in it and I finally found that sweet spot around 800rpm or so, anything below that it starts throwing a damn fit and surging and running like shit.

Thank you for this video! Gonna do this to my fox! Your videos are always awesome! Thank you for helping keep these cars alive!

Thanks for this video. I just bought a 1990 SSP in Colorado and drove it home to Atlanta. Thing bucked hard when just trying to stay at a steady speed, I always had to accelerate or decelerate for it run "smooth". Also, idles at 500 when hot (has an unknown aftermarket cam). Found two massive vacuum leaks in the lower intake gaskets. Going to change those, then follow your steps in this video. Your content has been gold to me since I've never owned a Foxbody before.

I used to do this to my mustang but it's been a while helped me remember the .999 for the TPS sensor thanks I was about to look this procedure up

Dropping knowledge as usual!👈💯🔥

It’s a very important point that with an aftermarket cam the idle speed must be raised above factory. How much is necessary will depend on how aggressive the cam is. Years ago my best friend and I straightened out the idle on countless modified Mustangs that we met around town. The common denominator was that the owner/builder was trying to idle the engine too low and they had the usual surging idle. Up and down, up and down. What few people realize is that when you try to idle a more aggressive camshaft too low is that it creates “intake reversion” which is a reverse pulse through the intake tract all the way out to the air filter. This is because more aggressive cams have more valve overlap, the amount of time both valves are open at the same time as the exhaust stroke is ending and the intake stroke is simultaneously beginning. Imagine a situation where your MAF is reading incoming air one moment then suddenly not the next moment like someone turning a light switch on and off rapidly and continuously. So one moment the computer is seeing air flow from the MAF then it’s not. The computers reaction is to raise and lower the ignition timing to match and that is where you get the surging idle. Sometimes the surging is consistent and other times it’s a runaway situation where the difference between high and low grows wider and wider to the point where the low is so low the engine stalls. If you put a timing light on while the surging is happening you can watch it shoot up and down, up and down, up and down. All these people would put those goofy adjustable spacers under the IAC when the surging idle has nothing to do with the IAC. It’s all because the ignition timing is going advance then retard because of intake reversion. You have to increase the idle speed enough to get passed the reversion to where you’re getting a consistent, continuous intake reading from the MAF and then like magic the engine will idle steadily. We typically found 850-950rpm to be the happy range depending on the cam used. All these people thought we were magicians when in reality we just understood how a more aggressive cam changes the dynamics of an engine. Intake reversion can also play hell with idle stability on carbureted engines.

I love how clean under the hood is on the retro fox

Always teaching the basics to figure out what adjustments to make for each component for what they change, always informative. When you got Andrew's car were thinking about bombing for spiders again?

Man when you show Andrew’s engine bay and then show them engine bay in the retro fox, it’s so clean compared to Andrew’s. God Damn!

You’re a cool ass dad, man.

Very helpful thanks for the video

I love this channel.

Good stuff!!!

Nice. Helpful.

Thank you for the video learned something new

This is great info, thank you for putting this out there. I have a 95 with the 5.0 h.o and it supposedly has a e303 cam but is doing the idle surge and feels pretty sluggish, i would like to check the timing but the distributor is actually stuck. What would you recommend to get it unstuck?

Great Video...a few questions. Does the car need to be at operating temp? What are your thoughts on aftermarket throttle bodies without the small hole in the throttle blade. I'm running a 70mm and it doesn't have a hole where as the factory ones do.

Love the way Andrews Tires look. I have similar Eagle 4 bolt rims and want that exact look. What size are Andrews tires front and back and has he removed or flipped his quad shocks?

I have a 88Tbird stock 5.0 EFI 5spd swap, 99 Gt axle and front hubs. I have these idle problems. Thanks for video.

hey love ur videos been very helpful. but im currently stumpped and been tryna find a video with my problem but havnt. so in my situation i have a 87 foxbody but car wont let me try to do timing with the spout connector removed. i even have it running and pull it out and just shuts off . been frustrating. the owner before me has a mega squirt ecm. i dunno if its cuz of that

Hey man great video will this procedure be the same for a 90 F250 460 EFI motor thank you

The bucking is what I’m having driving around the neighborhood. I didn’t know how to put it in words. Resetting the IAC as shown may help? I have installed E cam, heads, lifters, injectors, MAF, cold air intake, timing chain new IAC.

Hey, thank you for the video. I replace the engine and basically everything. Recently put a new throttle body on followed this video. Idle is pretty good but took it out for a rip got home and the idle bogged down and the car died, I started it gave it a rev and it the idle caught itself. Does this sound like the computer is just re learning everything?

This might be a dumb question but I just went carb on my 87 lx I’m running a 6al box and a hei dis. What wires on the harness can I get rid of. I was keep ac I know the alt and I’m keeping the oil pressure and coolet temp

Love the videos man! I have a 93 fox. What would cause my RPMs to hang up around 1500 when i let off the gas. Then if I blip the throttle, it returns to normal?

New subscriber here, I noticed you have done these on the 5spd cars a couple times. Is this going to be the same for AOD cars? I have a random high idle (hot or cold) and will stop if the engine is turned off then started back up and looking into it this spring.

Great video.. I tried setting the the base idle and now the engine won't start. Any suggestions on what could have happened? thanks

Hell... 😏Thats bout what my ish sounds like after my green ass starts tryna pretend like i kno what im doing!! .🤦🏼‍♂️ LMAO fr! Thats why i come here for fxbdy wisdom!! Luv tha ch. nvr miss a vid and jus like right now, i end up rewatching most videos multiple times... I Watch the hell outta them shitz

Do you set tps voltage with idle screw all the way out? Or use the idle screw to achieve your .98 volts?

I have a quick question. I can not get my tps below 4 volts for some reason. I'm not sure if it's something I have done or what. The timing is set right so I'm lost.

Great video, would you happen to be able to do one for Carburetors? How to adjust your carb for idle? Have an 85 GT new to learning about Carb cars

Timing without spout should be at 10* from factory, it’s the default when spout is removed. And once plugged in it advances to where it needs to be. This save a bunch a time.

Hey bro,i just bought a fox body and it has a coil pack, it's the same procedure???

After you take it again and replace those headlights @Kevin wines suggested you do, you should detail the engine bay for him! LoL

What is the best wide band sensor kit to use with the mega squirt?

If I have a sound system, should I unplug my power wire running from the amplifiers to the battery when running the car with no load?

Would the basics of this still apply to me having a cammed 5.0 in an Explorer application. Major difference being I have ignition coil packs instead of a distributor?

Would this apply to a 1995 mustang with stock computer and a foxbody throttle body set up?

Can I do this on a car that has a tune? My car idles and runs great but has idle hang when I rev it. I’ve tried motor craft and aftermarket iac and no help

My fox is on jack stands is that good?

2 years later and after modifying my fox I’d like to this video done again with a h.c.i fox.

I have a Trick Flow top end kit. I have struggeled with idle and stalling. I just got it to start and idle nice, did the base idle reset. I had no difference in rpm`s when unplugging / plugging the IAC. It idles good around 750-800, timing 12-13 and TPS 0,98. But if i rev it and let go of gas it stalls, wont even surge. Also when releasing clutch it stalls. It sometimes struggles with start up and idling but ends up idling perfect, but stalls if i rev it and let go of gas🤷‍♂🤷‍♂🤷‍♂🤷‍♂

How much timing should I put on a 95 mustang gt with full exhaust and cobra lower and upper?

Thank you for that information. I have done the base idle reset before, but I never shut off the engine before reconnecting the IAC. I am curious though, if I connect the IAC while the engine is running, will shutting it down and restarting it do the same thing, or does it need to be disconnected when it is shut down? Also, my car seems to be running really rich. I am running a basically stock rebuilt 1986 HO with an A9P (automatic) in my 1967 Galaxie 500. The only mods I have from the Mustang are long tube headers and the smog pump and cats removed. It seems to run great, but really rich. Any help would be appreciated.

I've been having issues with the iac valve I've replaced it 3 times even got the original part.number Motorcraft from summit racing runs great for a month then dies at cold start and will stay running when warmed up any help is greatly appreciated

my pcv valve was bad and it caused me all kinds of grief with idle realized it was bad and replaced it idles perfect now I could get it to idle for little bit think I finally got it go for a drive and it would start acting up again it was so frustrating the old saying if you shake the pcv and it rattles it's good not true

My car sat for years and I got it started but it idles super high around 2k. Could this be the issue or maybe sticking TB or IAC?

I just did this with a new IAC. it was idling way high so I unplugged the IAC, it dropped down where it should be and when I cut the car off, plugged the IAC back in and restarted it, the idle shot way up. Back to the drawing board....

Hey Brew, I’ve got an IAC that sits at 5-6V when running, is that normal?

I need help with my idle issue that just started on my 1990 gt, it will idle high around 1200 and sometimes up to 2000-2500. I’ve set timing, factory set idle. When it idles high, I can turn the car off and re start it and it will idle back down again. Replaced Iac and tps with no change.

I’m having idle problems with my 95. Iac unplugged it idles rough and sounds like it’s cammed. Which guy i got it from said it had work done. Iac plugged in it shoots up to 1,500 rpm at idle. I’ve tried everything Ik. It also smells like it’s burning very rich and smokes when u romp on gas

does a base idle reset effect your tune?

Anyone know the secret to get a seat belt to retract..my kid pulled it out to the max...not looking forward to pulling of the moldings from the door to the hatch

Would a Power Probe be ok to use ?

Andrew has a great little notch there don’t he?

I have one screwed up Foxbody, I wont lie.

Same procedure for 1994 5.0 ?

Does this reset also apply to 94 to 95 Mustang gt ?

what can I do without a timing gun to set mine

brew, what socket size are you using on the throttle body screw? im pretty sure my screw is either broken or somewhat different. have never been able to mess with it because it doesn't look like an actual screw, just the threads basically. I got a bcam so its hard enough to make it idle without warming it up a little

The same way the factory idle reset is done I wonder if it makes any difference if you do it when running a Terminator X I'm going to have to give it a try and see

😂 your gonna have a base idle reset series

my car has a b cam and the rpms fluctuate from 800 to 1000 when at idle. is that normal?

@BREW2L great video. Do you know if this can be used on the f series trucks with speed density?

I’ve done the base idle but hot start is💩 with surging that sometimes kills the engine. It was suggested that I start the car with the alternator disconnected and see. Unplugged the alternator and it starts right up and idles like BUTTER! Plugged it back in… surging! Alternator or wiring? Opinions please and thank you! Sten

Hey. Long time watcher. Looking to building a garage. I was wondering what the dimensions of the building is?

Watch that fan blade,work from the left or right side,

Take Andrew's fox and put new oversized tires and brakes disc all four

Can u do something about TFI overheating?

My biggest issues is now that I've done the Idle Reset, The Spout doesn't seem to do anything. When I tune the car to 12-14º it runs just ok. I noticed my Timing does not move with or without the spout connected. RPMS doe not move when it's connected or removed. I've tried a jump wire and checked volts on the spout and everything seem to work. Timing does not move with or without spout. Help. 🙏🏼

I need to bring my car to you lol

Can you do a base idle reset if the car isn’t fully warmed up?

Come do mine next please

Base it brah

Can you please Polish them Headlights!! 😳

You should never touch the screw on the throtalbody!!! Now its really messed up. Throtalbodys are adjusted on light table and now you go turn it so if u set it at 98 tps its going to be off because u turned the screw and of course its idle is to fast.. recalibrate lol... ok

What would cause it to surge at idle?

It needs a terminator x

Its already dark outside took all day and night for you to halfway keep it running. I bet wot is all messed up.

Straight up cloak and dagger shit!

Watch the accufab video on RU-vid about turning the screw. Big no no!!!!

I only seem to be able to get .20 on my TPS when I check the voltage. KOEO... and from eyeballing it it seems impossible to get even close to any acceptable ranges.

25HP with a BIR

spare your time.. go carburetor and nitrous be gone efi...
