Missfire at Idle HELP!
Vehicle:
2000 F250 4x4, V-10 Auto, 130k miles
Problem:
Truck rough at idle- surges, sounds like it has a wicked cam in it. No check engine lights. Tried OBD reader- no codes, but it did show an intermittent missfire. No hesitation, miss or lack of power noticed at driving speed or while accelerating.
After reading a bunch of threads on here about missfires and surging/ hesitation- I tried new coils and new spark plugs. Got nothing. I am at my wits end with this thing... Any ideas??
Update- Removed, cleaned and reinstalled IAC... cleaned MAF, reset computer... no dice...
