I agree with Pete. The symptoms you describe sound like a vacuum leak. I have had it happen to me. Did you put o-rings on all 16 injectors at the injector housing. Some year LT5's require an oring that is in the housing.
Try removing the bellows at the throttle body air horn and block the air flow to the throttle with a STIFF board, a binder cover works well. With the air horn blocked, the engine should stall. If the engine doesn't stall, you have a vacuum leak. Good luck Jim |
