View Full Version : Replaced my IMRC today...

Recently, my car has been running like hell. I ordered an IMRC from Team Ford and it was here the next day from California.
That thing was such a ***** to replace. I tried doing it without taking off the intake at first, and it didn't work. I ended up taking off the intake, throttle body, and the bracket just to get to the thing. After it was all apart and put back together, I was cranking the top bolt to the bracket and snapped it clean off...:banghead:
This was my first time actually working under the hood, and with all the dicking around, it took me 3 hours. I also didn't know the size tools I was going to need but all in all, it was easy. I have no more hesitation, and it pulls like a bat out of hell.
There really is no real value to this, just thought I'd post my experience.

I think it was just the angle I had it at, It wasn't even down all the way and I gave it one last crank and it snapped right off.

I jsut replaced mine about a month ago. I took off the intake and TB bracket also. the only real "problem" I had was getting the cable connected back to the LIM. lets just say you gotta push REAL hard.

You shouldn't have to take the intake off to replace this. this is one of fords over priced over quoted replacement parts out there. yes they would charge you to remove it but they wouldn't actually remove the intake. Its like a 15-20 min job with the right tools.

Wow man, that's pretty crazy. Anyone with a decent sized hand CANNOT get back there to disconnect those 2 clips on the end. That was the hardest part. This was also my first time doing ANY engine work (besides putting the intake on) so I was experimenting a little bit. I even used all the bolts I took off again with no extras! :banana:

I removed the throttle body and intake to replace mine, but not the upper intake manifold. Not sure if that is what you are talking about.....

at what point were you experiencing hesitation... like RPM wise and gear

@Wade: Didn't take off the UIM. Just the TB and the bracket as well as the intake. Plus I was just scoping some things out.
@Scrup: It was happening about 90% of the time at 4k. Other times it would kick in, and slam shut at about 5k.

wow, i remember mine was a pain just because the damn clip on the end of the wire was all warped for some reason like it melted. only took me maybe 45 minutes.
wait till you have to replace your starter. theres a lot of random crap that has to come off.
at least you replaced it and you're back to full strength....hopefully.

Definitely back to full strength. It feels soooooooo good punching the gas again and not having to worry about if my secondaries are going to open or not.

How much do IMRC's run? I just purchased a 2000 v6 cougar roush edition yesterday and I am experiencing extreme dead spots starting at around 3500 and most notably in 2nd and 3rd. Plus, I have a sorta rough idle, especially when I first start my car, usualy around 1400. It will calm after I drive for a minute. Are these things you were experiencing too? Sorry for the Newb question. Sounds like I need a IMRC replacement though.

The Intake Manifold Runner Control (IMRC) should not adversly affect idle unless, maybe, it is stuck in the open position?
Typically when the IMRC goes, you lose "top end" performance or, you experience a hesitation under acceleration at around 3500 rpm (when the IMRC actuates and opens the secondary butterfly valves).

davegregoire, sounds like you do need a replacement. and I got mine shipped to my house for $167, next day.
@99mcougar: What's the fun in that though! You gotta get your hands dirty.

Mine just arrived, it was $179 Canadian ($158 Yanky bills) and that was shipped by air to BC Canada.
I am going to my garage tomorrow and we are going to relocate it just behind the battery, sorta under my Ram Air. It should be pretty easy, there are already a couple holes ready to bolt a bracket up to (we will fabricate what we need there onsite). This will lower the heat level the IMRC has to endure considerably, which is what the manufacturers should have done in the first place!

Not that I know of. It isn't bad at all though. Very straight forward.

Nope but i can give you a little something:
Take the Duratech cover off the front of the engine. Than un-bolt the IMRC. Follow the cable to the LIM and disconnect it. Than bolt the new IMRC up and run the cable like the old one. Than connect it to the LIM. Now to get to the LIM you are going to have to take the UIM off. Some people might say that it can be done without taking the UIM off and sure anything is possible but its very easy to take the UIM off to make the job a lot easier.

I took off my intake and throttle bracket and it was easy.

I did it with the UIM on, but I pulled off the throttle body, throttle body bracket, and part of the intake.

Or, instead of going through all that hassle and spending $150+, how about spending $2.00 to fix it with this (http://newcougar.org/forums/showthread.php?t=99342) little mod. ;) Your welcome.

Also, FYI the transistor that you need is TIP102, not TIP120. I posted a link in the other post of the ebay seller that I got mine from for $1.98 shipped, he's got 8 left.

If you remove your UIM, you are adding a good 30+ minutes (or a lot more, if you've never done it before) to the job, and you are also going to stress the gaskets, which can lead to vacuum leaks and CEL's, unless you pony up the $30 to buy NEW gaskets.
Not worth it.
mond12345

Well if you remove the UIM than just clean it out really well than its worth the $30 for the new gaskets.

what is the difference between the tip120 and the tip102 and has any one tried to do this fix for there imrc and it not work ,what am i looking at maybe busting buy trying this ...from what ive learned so far if it sounds like a cheap easy fix it most of the time ends up costing me more. thanks for all the help

The TIP120 has a collector-emitter voltage of 60v and a collector current rating of 5 (continious) and 8 (peak) amps. The TIP102 has a collector-emitter voltage of 100v and a collector current rating of 8 and 15 amps respectivly. The stock transistor is rated at 100v and 8 and 16 amps. I have yet to hear of this mod not working, but hey, there is a first time for everything. lol The worst that could break? Your already dieing IMRC. If that happens, then you've only spent $3, and you have to get a new one anyways. You've really got nothing to lose buy trying this mod. If you follow the links, you'll eventually run into a how-to over on CEG.
