STOP BLAMING YOUR IAC VALVE! There could be other factors at play here (FOXBODY)

Sometimes when a battery is weak or old will cause the alternator to work more, thus putting excessive load on the engine causing idle fluctuations. This was the problem on my 86 fox.

[@ryanoshea6169]

If you have a fairly aggressive cam, the IAC becomes crucial for drivability. If you want the car to idle low enough to sound awesome and not die during higher RPM declutch, you need the IAC to catch the RPM drop so it doesn't stall the engine. This is called "dashpot" and more specifically "dashpot decay rate". I worked on mine using Moates Quarterhorse and Binary Editior.

I bought this 90 Ford F350 in Illinois up north, brought it back to Indiana, Inpls.. It had an idle that's not normal. Starts right up. And is a little high feeling normal. Run a minute, and tap throttle to bring down. Seems cool. Then tap again, and it's idled back a lil up high. Will do the same while driving. And didn't want to hit over drive or final gear. Ease back on throttle, and then it does shift. But get back on throttle And shifts back down. Done this for many miles.. Then I drove 65 more miles south and sat for almost a year while another bed was installed to convert into a wrecker. Finished that and brought it back to Indpls and was doing the same thing... Ok, now.. I had to do some Hydraulic work. So it wasn't being driven again for many months. But idle would still do the same while testing things. So I was told to replace throttle censor. Or positioning censor in Intake. That corrected the throttle some.. Bringing it down, and then it would shift out on test drive no problem. Some more time goes by testing equipment in driveway. Thinking all was fine. I get legal and drive it... BUT NOW.. It has some popping up front, and backfire in back through exhaust. I replaced many things, with no results.. The Smog pump stuff was partially disconnected from Illinois long time ago by previous owner. So I'm dealing with that too. SO.. Distrib Cap = nothing Wires = nothing 2 Vacuum hoses replaced = nothing. No results. Replaced fuel something on F/rail = Nothing. Then Plugs = BAM!!! It stopped. About 20 miles later, it starts back up again. Not as bad but same backfire.. So when I replaced the throttle deal, and removed the intake with the two large port holes, there was a gasket behind it. It looked good for being there. No rips tears or burnt marks. I cleaned a little and put this intake back on.. It's the only thing left that's different from purchase time. Is this where this backfire is building from? Cause I'm about to rip it back off and see.. But $250 roughly to fix this problem with a small result after plug change. Any idea's.. Try this and try that has gotten expensive. LOL

[@dntlss]

So cool to see young people getting pumped up over these cars,its like 1990 all over again,lol,i have a couple of these cars, a 89 i bought used and my 91 since new,we were dealing with these idle issues way back when,thats always been the battlefield with these cars,they are great cars though,affordable fun for the masses, at least back then, they are starting to get price crazy these days.

[@Markov_727]

I got an 01 gt and every now and then out of nowhere would give me a misfire. I cleaned maf changed coils plugs tps also cleaned camshaft position sensor crankshaft position sensor. And the damn misfire was still there. So i took the iac cleaned and all and the misfire was still there. This time i took it off again and inspected the thing and I blew on one side covering the other end and I fond that there was leak. The weird thing is that on this year model the iac has some sort of button/knob on the top. And that's where the leak was coming from. So i popped the knob and it was attached to a little pipe. So i covered the end with electrical tape and the misfire went away after months and so many hours of work and troubleshoot. But I just wanna thank you because your simple informative video made think twice about the iac.

[@scooter8187]

That black knob on the iac on an 01 is a vent cap. I don't know why covering it up would solve the problem. Probably need to replace the iac. Sadly, Motorcraft isn't making them any more so you'll need to go with an aftermarket version which is hit and miss.

Not sure if this will help any of your problems, but I built a 5.0 20 years ago, and had idling issues since day one. Life kept me busy so it actually sat in the garage, and would take it out occasionally. Maybe 200 miles a year. Anyway, now to my fix. I had the itch to drive it, and was determined to find out the problem. I first sprayed throttle body cleaner all around to find a vacuum leak, but did not find anything. I finally started with the base idle set, and no success so I knew it was something else. I then went to check fuel pressure, and when I removed the vacuum line on my BBK adjustable fuel regulator, it was spitting fuel out of the vacuum port. I found this was an issue from brand new on the model with the vacuum port that comes out the side of the housing. They improved the internals on the newer versions where the port is vertical on the housing. If anyone has an older BBK adjustable fuel pressure regulator, the first thing you should do is remove the vacuum line, put your finger over the port and a finger on the vacuum line. See if it idles now. Mine started idling as soon as I did that. I just put in a fixed regulator from Autozone for the time being in my car, and it idles good.

[@dntlss]

Like you i have been involved with these cars forever, dont see many people call them 5.0 these days,we never called them Foxbodies back then, ever,i have never heard good things about those BBK regulators, funny thing with adjustable regulators is that unless you are putting out massive numbers or your ride is forced induction they are nothing more than a gimmick, something to buy from Summit or LMR when payday comes,that good ole stock regulator will put your ride exactly where it needs to be, 39 with vacuum unplugged, thats all there is to it,if i had all the money back i spent 25 years ago on unnecessary things for my Mustangs i would be rich but it was soooo much fun getting that stuff in the mail and installing it,lol, guilty as charged.

[@RUNINAGT]

I'm having an idle drop issue when you clutch to come to a stop. Most the time it drops once, then smooths out. If I turn the AC on, you have to be carful to catch it before it stalls. Now just HCI on it. Got it tuned and car runs great. Hers's the odd part. After a change to try and resolve, Car will have a great idle and the idle drop is very minimal, I guess how it's supposed to be. After about 100 miles, it comes back. This time I replaced the IAC and took it on close to a 2 hr trip to hit a Fox event. Car ran and idled better than ever. Once I got close to home it was starting to get the idle drop back. Drove 2 days this week ad it's back. Mind you the car runs great, and idle is great. Only issue is when coming to a stop. Prob 70% of the time the idle drops. If AC is on, it drops harder. What could cause it to react great to a change, only to go back after 100 miles or so? Again. She runs great. Idles great, heck yesterday I sat for 30 mins idling with AC on and never even bumped. Just steady. It's almost like the computer keeps going back to a diff setting. This car was an auto car and still has same computer. It's now a 5spd car, but we corrected the harness to the vss and used a chip with the quarter horse tune to dial it in. Tuner and myself are about out of options.

[@mikemarks1834]

fordtechlife First of all I like to say I appreciate it for trying to help me out so this is what I’ve done it’s a 1986 Mustang GT five speed the car was sitting for about 10 years I pretty much restored everything that needed to be done so I put brand new plugs Motorcraft Ford racing wires , rotor and cap Motorcraft and a Motorcraft ignition coil I took off the intake and I replaced all the vacuums and replaced even the EGR pretty much basically I covered everything except for the coolant temperature sensors

[@bjmcacc2304]

What about the load of a manual transmission, i get intermittent idle surge (high RPM's) when pushing in the clutch while in park or neutral to shift into gear.

[@tanchelm]

Same problem here, have you solved yours?

[@pamelavance648]

​@tanchelm any results??

[@LuisGarcia-qd3qx]

I just bought a new motor craft iac and the idle is still high . You think I need to clean the throttle body?

[@balitrix]

Another easy way to figure out what the hell is going on with these cars is a OBD1 ford code reader on amazon or autozone for under $40, mine has helped me out a lot lol

[@allenjay5907]

I had to put an idle plate on mine to get it to idle right with b cam . It’s nice

[@daviddowns7552]

my car dont have idle adjust screw.

[@OfficalSnowyYT]

When I drive my car my base able is at 1500 RPMs not sure if that’s a tune or is it my idle needing a reset ,lately when I drive or sitting at a stop sign but I will shoot up to 2000 or 3000

Im having an issue on my 88 tbird 5.0 where it starts surging on when warm, especially when accessories are turned on. Idles around 1000 rpm in park. Also when i put it in gear...the idle is fine for about 4-5 seconds then starts surging, sometimes completely stalling. Could this be a bad temp sensor, spark plug, mass air meter, or ECM? Very frustrating. I tried doing a base idle reset and still doing it but 1000 rpm was lowest i could get it to idle in park. It's an E303 cam with GT40 heads, intake etc... mass air conversion from speed density. I heard the wrong torque converter can cause it but i dont think that's the issue. I have a 2200-2400 stall PA converter. Also have all smog and egr deleted, as well as any unnecessary vacuum lines. New motorcraft tps and iac as well.

Brew2l if my idle is doing exactly what your car did when you unplugged it what do you think because sometimes my car idles smooth and then randomly very up and down idle way too low and high it shouldn’t jump as much as it does and sometimes so low it stalls out . Just asking because I am going to follow your base idle reset video but is it a possibility u think it sounds like that iac ? And I’m going to go try the steering wheel turning to see if it corrects it but it’s crazy cold in New York that’s why I am asking because I’m waiting for spring brotha lol thanks for the videos always good content bro

[@jamesriley4102]

Can you still adjust the throttle stop with a mega squirt? I was under the impression it will mess everything else up.

[@BREW2LFOXBODY]

Absolutely you can 👌

[@jamesriley4102]

@@BREW2LFOXBODY Awesome. Thank you sir. Your mega squirt videos have helped a lot!

Sweet looking ride!

Bro Merry Christmas listen I have 1989 Ford Mustang nobody can fix it can you fix it for me I like your show

[@antiup-boss5848]

89 GT won't start when cold, push it outside in the sun and after about 10 minutes she fires right up. Any suggestions on what the problem could be?

[@danb.3397]

Good info. Just picking at nits .....it's EDelbrock.

[@jonnypistolero]

What are you using for EGR plate and EGR sensor plug to not throw the CEL?

[@Vickyvee97]

Actually all carburetor's have an idle control circuit inside of them, if their blocked they cause a rough idle or no idle at all.

[@nightmarebeats9531]

Love your videos man, been subscribed. Have a question for you if you have a sec, i own a 1989 5.0 5 speed convertible. Im getting voltage drop that will randomly go away. Sometimes will turn my aftermarket head unit off then back on. Checked my connections everythings good behind there, amp is bypassed and run off an aftermarket one. Random alternator feedback through stereo is happening. At WOT in low rpms sputters and jerks. Swapped out the distributer with an msd streetfire and a bbk tps sensor and the sputtering went away for the most part but is still there slightly.. Still getting votage drop. Before i installed the msd distributor i couldnt install either or of the bbk tps sensor or msd ignition coil without making it run like poo.. Any info or tips? Run into anything like this before? Running a stock alternator aftermarket head unit 2 8" woofers with pro tweeters and 6 and a halfs. Aftermarket spyder tail lighs and head lights.. Thanks for your videos bud helped me out a ton!

[@fordtechlife]

Dam that's some weird shit you might try upgrading to that 3G alternator if you haven't already I'm getting ready to do that when my sub hits hard my lights will dim a little and my alternator gauge to twitches 💪🔧🚘🇺🇸🦊
