98 Expedition, Idle @ Startup problem
Thx for the advice, I'll replace it this weekend and let yah know how things turn out. I already have the 'special tool' in my tool chest so i'm good with that. Also thanks for the AutoZone tip, I didn't know they performed that service (pull codes).
take care,
Lin
I think the 4by4freek is probably your best bet for an answer to this, 4x4 has this earlier reply on this thread: "use the search on this site for GEM Module. This should give you the answers you need." try that and see if it gives you the data your looking for.
As far as my earlier problems, the IAC replacement and throttle body cleaning have eliminated the problems that I was having, the IAC replacement probably would have done the trick by itself, but I had the throttle body done first in the sequence.
good luck..
