CAN SOMEONE HELP
How long have you has the Granatelli MAF and ported TB on the car? If it has not been on the car long your PCM might need more time to “learn “it.
If the above is not the case, re-install your old MAF / TB setup and see if the problem is corrected. If you still have the problem then you probably have a bad or dirty IAC.
Good luck

did the car do this before the installation of the mass air and t-body?
if so, its normal.
if not, then go back and recheck all of the hose clamps ect. sound like a small vacum leak somewhere.
if every thing checks out fine, swap your stock stuff back on.
see if the car still acts up.
lemme know how it works out.

The dealer said it was the PCM idling up to help with gear changes, what do you guys think?
Thanks. Scott 00 WS6 M6.
