Re: upper intake gasket Sign In
MMMM....Double and triple check all the electrical plugs and vacumme lines. Make sure your injector plugs are plugged into the correct injector. Have the codes pulled. there will certainly be a miss fire code but there may be something else there to give you a place to start. Also if I remember correctly there is a vacumme tube inside the upper intake and if it falls out it can give you some trouble. Also if you accidently dropped some junk down in the intake it could cause a valve to stick open. This happened to me once on a 3.4(piece of gasket material). Spent days chasing the problem. Has something to do with the recent work so recheck.

Check firing order. You may have wires crossed.
