Thanks for the great write up. Had the cel popping up till it came on all the time. Pulled the imrc today, didn't desoder anything just took screws out and used a screwdriver and sand paper to get between the contacts. Didn't get to test drive it yet but when I started it the manifold was pulled closed and the cel was off. Hopefully stays off for a good while.

My fix did not work. I did this back in Nov. resoldered the joints, cleaned the contacts and put everything back. got the CEL within a day. I'm getting ready to get a used one from a pull a part to see if it really fixes it before I try a new one. I hear that several other models use the same box with different cable legnths that will swap right in. I know of a couple of guys who installed a new IMRC to only have the code come right back.
mine pulls the lever at start up then releases after a few seconds. then the code comes right back if I reset it.

ok, I can verify that a IMRC from a cougar (99-02) is the same as the focus. The cable is slightly longer (2 to 3 inches). I just put one on mine and it has fixed my issues. The old IMRC actuated the lever slowly then snapped back to the long runner position after starting and I think this was the whole problem. Probably a timing issue in the activation of the IMRC circuit. The replacement box actuates much quicker and holds there just like it's supposed to. Taking off is so much better with the added touque on the low end now.

Changed my imrc today and it made a difference. Only problem I encountered was trying to remove the air box, Make sure to just pull really hard straight. I thought it was bolted. Also getting the old cable off the plastic, I just got some pliers and broke the tabs. Gas milage is up. Thanks for write up!
