I got the leaks out of my exhaust and lubed my IAC plunger. After that, I get 327, 411 and 412 which all has to do with the IAC I assume. The idle sits at about 2k and theres nothing I can do to get it down. Did I fry the selonoid maybe? I only lubes it cause it was stuck and the selonoid looks to be seperated from the actual plunger...

Ill probably replace the IAC but anyone have any suggestions before I do?

Anyone know what those codes could mean then? I replaced the IAC and it didin't to crap..

I "belive" that 411 412 are idle problems when running KOER test when idel can not be contorled, I also belive that 327 is an EGR code. an EGR problem can effect the running test. the IAC doesn;t need to be lubed in fact most of the fords are not cleanable. I sugest getting a new one just to eliminate that. I would also be thinking about the egr. If you have the ability to scan it and see what the desiered position and actucal position and see if itls not holding. YOu might also remove it and inspect the passageways to the intake. Then clear the codes and see what comes back

EGR was taken care of, IAC was replaced same problem. Idle sticks at about 2k rpms...

What about your timing? your MAF?

Milky

Timing wasn't touched... and MAF worked fine beofre and still does just not at idle.
