Also, don't block off FIAV. YOU'LL NEVER IDLE. more problems then you have now.

Base idle set screw ;)

The FIAV should only be open when the engine is cold, if it truely is the culprit it is b/c it can't shut once the engine warms up. Blocked off the car should idle as if it were just closed as it should be. Warm-ups in the Winter (still moving back to MN?) will take a bit longer and cold-engine idle will be a bit low.

i am moving back to the TC. But when I do, the car will never be driven in the winter. It's an AZ/Nevada car. No rust what so ever. And I'm not gunna ruin that. Also from what you're saying, most likely the faiv is stuck open. And under normal cold start conditions it would also be open. So then shouldn't it idle normal, just high because it's stuck open, so it'd be like its thinking its cold the entire time? I dunno. I'm still thinking I'll just wait for my buddy to come back and put the bottom half of his TB on mine and see if that fixes it. Thanx for the help. Also JasonR, you are more then welcome to stop by to help me out with this. I live in Yuma, AZ. It's right on the border of AZ, CA, and Mexico. are you anywhere near me? :P

ok i just got done swapping out my throttle body with one from my buddies laser. Not only did the idle surge go away, but it also got rid of my mysterious "slowness" the car has always had. Looks like im buying me a new throttle body!

Ahh so I was right ;) :bounce:

COOL, you got it, Congrats. FIAV is culprit!

ya im really guessing its the FIAV, but imma just get a whole new TB. I don't wanna mess with trying to get just half of one or whatever. thanx for the help though everybody!
