thank you for the responses Clinton64xl and Cole_CT
Will do (vaccum leaks). Air filter has about 1,000 miles on it. The throttle body was cleaned when i did the IAC replacement (about 800 miles ago).
Personally, i am not a huge fan of spraying very flamable chemicals around a running/warm engine. Usually to find vaccum leaks, i will unhook a a line, apply vaccum with a hand pump/guage and verify it holds. it presents a little less of a fire hazard and can be done when the engine is cold. I'll probably pull the upper/lower intakes and replace their gaskets just to be sure. The gaskets are cheap and my labor is free. it will also give me the chance to port match them.
I also saw on another forum last night, a guy had very similiar issues to me and found significant damage to the computer/harness connector. I will be checking that tonight, too.
