First of all confirm the connectors are attached to TB and that the TB blade is closing completely.

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

first order of business is this.

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.

Well, I haven't figured it out. If I coast with clutch in or out my idle stays at around 1100-1200rpm untill the wheels stop, then it will drop to normal, I'm stock (besides lid) and it has done this from day one.

The dealer said it was the PCM idling up to help with gear changes, what do you guys think?

Thanks. Scott 00 WS6 M6.

 

your dealer is right.
its for assistance in the shifting.

My 2000 SS does the same thing. At first, I thought it must have been because of "rammed" air still passing through the MAF, but I have block my hood scoop and the same thing has occurred. I would not worry about it

 

I HAVE A 2000 RAM AIR M6. I HAVE A LID,GRANATELLI MASS AIR AND PORTED THROTTLE BODY.WHEN I PUSH IN THE CLUTCH AND THE BRAKE TO STOP MY RPM DONT DROP RIGHT AWAY BACK TO AROUND IDLE.INSTEAD THE IDLE WILL GO TO AROUND 1200 AND STAY THERE UNTIL BASICALLY IM STOPPED(THEN THE RPM GAUGE WILL DROP TO IDLE). IS THIS NORMAL OR NOT. THANKS

 

I have a 2000 Z28 with the M6 but I don't have this problem. Although, I have read about several others on the SLP forum (SS Camaro) who have the same exact issues. I think its only the 02s
