I did follow the instructions on replacing the IAC per the CD Manual... Measured and set the length of the pintle. No need for the fuse removal because I had the Battery disconnected.
I'm leaning toward MAF or EGR... We'll see what the dealer says... When I get around to taking it in shrug.
have you tried checking your air-fuel ratio? you should be able to program the scangauge to show it.. mine always reads 14.3 (or is it 14.7... i cant remember)
