When my car warms up to normal operating temp, if I go to 4k+RPM, it will nudge back and forth with power, then without, then with, for about 2kRPM, then it loses that nice pull of the 2.5L. I have searched and read numerous posts on this and have figured that it's my IMRC.
Where other than a Ford dealer can I get one of these? Does Terry Hanes carry them? When will Bill Jenkins be back in business... and can I get one from him? Any direction as to where to go guys?! Any help would be great. Thanx in advance!

Pull the IMRC connector plug. Clean both ends. Reinstall coated with dielectric grease
Manually operate the secondary linkage full travel multiple times and check for binding or sticking.

I think I'd be inclined to find out whats wrong before you change it....check the cable at the linkage end is not broken....remove the beauty cover ...unscrew the IMRC cover....start the engine....hold the electric motor...blip the throttle from under the hood and see if the motor is operating the gears......

is the imrc box the one that sits under the 'duratec' shroud on top of the front bank valve cover?

Yes, the IMRC is the metal box under the plastic valve cover cover that says 24V... I didn't get a chance to clean the conection and such (this weekend was very hectic for me), but I plan on doing so today. The reason I don't think that the cable is broken and that the secondaries themselves aren't stuck is because before it goes out, it will open, then flutter a few times and then just quit trying and give up. That tells me that the secondaries aren't really sticking since they are opening... then when the car cools off even for a few minutes and I drive it again, it will work fine for a while again.

That sounds like a bad IMRC. Failing when it gets hot.
Mine did the same thing a year ago. When it got hot it would lose the ability to hold the secondaries open and they would flutter. It took a while for me to track down the reason why. (3 Ford dealers had no clue, not that that is a big surprise in the least :rolleyes: )

How much gas do you have when it does it. Reason I asked is cause when my did that about two/three wks ago Ford ended up replacing my fuel pump after two visits w/in the week. Sounds similar but could be mistaken. It wouldn't do it till about a little under a half tank, and then it was nasty. First gear it would start at about 4k and just shake kind of violent just like fuel cut. second was later, around 5k but you could feel the pull up to that point wasn't very powerful. Don't know if the same just puting in my 2 cents for what its worth.

Nah, this is definately my IMRC. It's hard to explain, but you can totaly feel it, and I know exactly what it's doing. I just need to get a new one now I think. I will dig in and check my IMRC box today (take cover off and troubleshoot) but I am almost positive that I need a new one...
Where is the best place to get a new one?
