I cleaned the IAC valve today with B-12 and a fine paint brush. It looked pretty dirty, but wasnt horrible. Also, cleaned MAF and TB. Put everything back together and she idles fine. Just curious, how important is it to line up the larger holes on the IAC gasket when re-installing? It has a little bit of play and when both bolts where back on i couldnt tell how centered it was. I took the car out for a test drive and it seemed just ok. I noticed a slight lag in powerband. Will it take the computer a little while to adjust? Thanks for the help...
