the car idles great but when i drive and come to a stop it wants to die. it almost dies and it comes back to perfect idle.. please tell me whats wrong.. just put new forged pistons in. and refreshed the motor. cc306 tea heads and a tune out of OKC...

 

i had the same problem with my old h/c build and was told its a tune issue. i forget exactly where but had to do with fuel and decel. i blew that motor before i could fix it but ask your tuner.

 

I would look for a vacuum leak or I would check to see that your IAC is working properly. It also could be a tune issue.

 

ok i'll look for leak then get a new IAC thanks
