Thanks for the insight Jim. I replaced the IAC valve today and am waiting to see if the starting problem is resolved. I have still noticed the "theft" light flashing a couple of times before turning the engine over. I'll keep you updated though.

However, now JUST LIKE TRW, I thought I'd be a good guy and change the plugs while under the hood. NOW IT'S RUNNING ROUGH. I took it to AutoZone for diagnostics. No codes. I checked the vacuum/PCV valve but the vacuum tube and valve both seem good. WHAT HAVE I DONE?
