Now that I've replaced any and all possible sensors related to idle time or fuel deliver, I'm going to have the fuel pump checked out. I've been wanting to replace it anyway since my fuel meter doesn't work anymore and the only way to fix that is to replace the whole damn thing .
Cycling the key you just turn it on for 10 secs then off for 10 secs. but it should have been done when it was replaced.

Your throtle body is the silver aluminum piece the IAC goes into, and the TPS is attached to. Probly full of carbon on the back side, thier is also a tiny hole in the TB butterfly that can get clogged and it can effect idle.

If your fuel filter hasnt been replaced in the last 20-30k miles you might change that out.

Yeah both my GAs have that floaty gas gauge, and Ive been waiting a long time to replace the whole unit but my fuel pump seems to just keep going and going.
My Se is creeping up on the 200k mile mark, it should be going any time now.

Hope that helps
