Since I added this 93 Cobra I have not been able to get it to idle with the IAC plugged in....
My old Explorer was mint...all I did was set the TPS and blam...it was on the money....this set-up has been a pain...
Finally after buying a used Fox IAC..i tryed it again....no dice...the idle would hang like a mofo.....DAMN...unplugged it again...
i searched around last week and came across this link in the 5.0 tech forum...

I followed steps 3 and 4 to a tee.....DAMN...I was rewarded with my old nice idle back....no more hanging, dying when cold in the morning, dying at a stop sign with the AC running...its freakin nice to have it back again...
the thing that pissed me off the most was my gas milage...it went to chit??? alot of that had to do with the TPS being wack....once i did step 3...i checked the TPS voltage (which i had set at .099 a month AGO) it was 1.3...hence i think, the hanging idle....I had adjusted the throttle for this intake install...this is a no no unless you re-set the TPS....I DIDN'T DO THAT BEFORE....
i reset it to .099 last nite...ran it to WOT 3 times over til it held steady when shut...i settled on .098...rechecked today and it held at .098...
not only does it drive so much smoother but my gas gage hardly moved, to and fro from work, 32 miles round trip....sucking fuel down bigtime???? this could be the culprit???
just thought id throw it up as i know others have have these issues to ....I'll be damned...this write-up works.....
