PabloFord Thanks, AMAWDS for your reply.

amawds So your IMRC is mechanically functioning correctly. You need to pull it apart and clean the contact inside. It's pulling the cable, but the contact is corroded so the engine computer can't see that it successfully did its job so it fails the self test and cuts power to the IMRC. Ironically the thing that's supposed to show whether the device is functioning or not is the thing that fails in it the most. However, that isn't the cause of any of your symptoms. The car will start and run just fine without the IMRC in working order.

PabloFord I'm a new SVT owner / driver and newby to this site. Purchased my '02 needing some work. Has an IMRC issue but after reading this entire thread I don't see anyone with the same. I do have the P1518 code but here are my symptoms: 1) constant shhh...shhh...shhh from the IMRC. 2) Slow to start when weather is cold, and must push throttle down or it will not start, and 3) Poor mpg - 24 in country and highway driving. IMRC is pulling the cable and immediately releasing it; repeat. Any thoughts?

Sniper Focus Sometimes I want to make another thread. first post is helpful, but not the best method. Then there's other good info buried in the 17 pages.

Remove all screws except for the two that hold the connector to the board. Dig the epoxy out from around the connector. I sealed it back up with RTV which is easier to remove for next time. I have to clean my IMRC about every two years.

But when I got it today the cable on it looks really short like I don't think it's gonna reach at all. Is there anyway to change the cables? Did anyone else get one of these and did it fit? I mean if it works since cable is so short looks like I would have to relocate the actually module to engine bay doe where close. I don't know
Didn't know Dorman made these... they say it's for a 96-07 Taurus. Cant trust Summit 100% if its not a SBF or a SBC.

You can open it and swap the cable, the board has to come out though. You can do it the easy way like me and use the non de-soldering method.
How did u do it without de soldering? U did the how to? Or you swapped the cable? Please let me know

pasta This is part of if not all your issue.

Billfromnj05 Quick question. I have cel on and it says intake manifold control stuck open code. So I'm guessing it has to do with the irmc module. When car idles it runs like crap spitter and sounds like it want ms to stall. And in low rpms when I go from a stop the car bucks like its gonna fall on its face and has no power. Is this behavior all from this box? So I have to do this how-to to fix it and it will get car back to normal?

jrose Yup, I did mine about a year ago and it's still working just fine. Rather than remove the headlight, however, I removed the left front wheel and the inner fender liner to get at the control box. It was really easy. I also used an ignition point file rather than sand paper. Old school do-it-yourselfers like me remember when our cars had ignition points that often had to be filed smooth and then reset. We were always told to use a point file designed for that purpose rather than sandpaper because sandpaper could leave embedded particles. In short, the write-up here was most helpful to me and I couldn't ask more for a result at what little this "fix" cost me. By the way, my toolbox no longer had an ignition point file in it, and the local Advance Auto had no idea what I was talking about. Amazon.com, however, was able to provide me with such a file.
