Idle problem after some work
It looks like I'm missing something because i cant seem to get this idle problem worked out. After blocking off the AWS and installing an efini y-pipe my idle has become very high at around 2000-2200rpm. I adjusted the TPS screw to the point where it was all the way in bringing the idle down to 1400rpm but I don't think having it screwed all the way in is the right fix plus the idles still high. I have a PFC, intake, and full exhaust. Any ideas are welcome. It was pretty dark when I got the UIM all hooked up could a incorrectly placed vacuum line be the culprit?

Only adjust your TPS if you are reading the voltages.

I assume you meant the air bleed screw on the bottom LH side of the throttle body?

Well there's nothing wrong with the vacuum lines but I think the problem was I forgot to let the car relearn idle after disconnecting the battery. Now for the new problem, what is the correct position for the air bleed screw since I messed with it?

I believe you'll find it in the above thread, I think it's a quarter turn from bottom, though you can adjust it to less using the two adjustment screws. Though checking your tps voltages is a good place to start.
