Alright, so I bought a 1994 Camaro Z28 with an LT1, I put a cold air intake on it, and now at idle the RPMs will increase and idle up, but then die, it also has a horrible hesitation in the throttle when im at normal driving speed, it shakes the whole car, but finally picks up, like I miss on more then one cylinder. Any help would be greatly appreciated. Thanks.

 

The first thing to check would be the intake elbow (right at the throttle body). It is hard to fit on the bottom side. It is also prone to tearing at that location.
