hey guys i have been having this issue for months now, before i did my top swap, intercooler and all other mods. i am putting on cylinder heads stage 3 zzps and xp hot cam in two weeks. anyway when i put it in drive after the rpms lower to normal about 850-900, i touch the gas to go and the rpms drop low and the car shakes than goes. the intake sucks in a lot of air and the car drives. only happens when the car is cold start. any ideas? to me its the pcm but it was properly dyno tuned. thanks
