August 2, 2007I recently changed out my motor from a V6 to a V8
Chevy stock long block , edelbrock intack , headers , msd coil and distributor , holley tbi unit , flex-a-lite dual fans.
my problem is that during idle its not smooth. i feel a slight bump to it. ive checked everything and even had it to the dealer , and cant find problem. ive noticed if i pop on the a/c i can bearly feel it if any.
any help ????
