I hope this is just it
Okay so my car has had some odd idles. And at soem times it will lack power when i hit the gas because of it. Like it is getting no air to go in. I honestly think it is the IAC valve or the TPS, more so IAC, because sometimes it runs perfect. I have messed with the torx bit on the tb without resetting the idle speed. I think that this is the problem. Now I was going to reset my IAC, but i was confused on the A and B pins. Can some1 give me a picture please?

Re: I hope this is just it
See if you have any vacuum leaks, it's usually the culprit. Track any port that leads from your throttle body or intake manifold, and make sure it ends somewhere contained. Usually you can find a broken line or two if you haven't been under the hood much before.
After that, get a vacuum diagram and make sure those lines are even going where they're supposed to. You'd be surprised what previous owners did with things that they didn't know where it went (took me over a year to diagnose all the problems the previous owner caused my car!)
Come back after you've checked the vacuum stuff and tell us what you've found.
