if its not one thing, its always another..

got this intake from someone this past friday.. and put it on.. noticed a misfire.. the intake has now been on and off the car 3 times.. the plastic clips are removed from the knock sensors and its sealed for sure.

but the damn thing still missfires.. went as far as replacing all the plugs with new ones.. still misfires..

so this misfire.. would there be a way to check and see if its the intake manifold or is there a chance that my car is too rich or too lean of a tune and its causing that w/ the new intake.. damn frustrating

Slap the LS1 intake back on and see if it still has a misfire

What shape were the gaskets in? Make sure you didn't miss the 3 connections on the back of the intake.
