Well, Here goes...
I got an all around running 87 T in August. But, the idle has been a little weird. IAC counts are from 55-65 in park, 60-70 in gear hot. So, I do the IAC reset procedure, it comes down to between 0-20 in gear.... WOW! I got it! Not so fast... It was good until, I shut the car off. Now, it went back up to 60-70 in gear. Which is not "all that" bad. But, the car still has a surge to it at idle I would like to resolve. (at least minimize)
The procedure I have done is the "IAC Reset Procedure" from GNTTYPE, and is from the service manual. When it gets scary is when I start the car with the IAC unplugged. It runs at 2300 with the throttle screw not touching the throttle arm. It will slowly return to 800-900 upon being plgged back in.
So, now the car still has a weird idle at times, and during a warm start will rev to 2000 rpm, before slowly droping down to "normal" rpm.
The BLM`s are at 122 hot and idling. So, it should not have any vacuum leaks. It had an new IAC put in yesterday.
I am stumped and confused. Any help would be appreciated.
