Do the lower intake as well using the fel pro problem solver.
I know this thread is about 2 months old, but id rather continue off this one rather then start a new one for people to search.
What problem does felpro solve on the Lower Intake? Is it a better gasket?
Between Delphi and ACDelco Upgrade which one is better?
I have to do this, My Injectors are bad, slight stutter driving on freeway, and the requirement of spraying starting fluid in the intake to get my truck to start after sitting for 8 plus hours, But no check engine light.
