My 2003 Nissan Sentra, SER is misfiring (no 1 cylinder) the dealer stated that they have to remove the head to find the problem. The dealer installed shorter plus fpr a quick fix but the vehicle is still misfiring only at idle speed.
I forget to mention that the misfiring also closed the electrude on the plug.
Warranty has run out. I need help or a solution.

Did you get the pre-cat recall taken care of? It sounds like the clasic symptoms of the pre-cat getting sucked back into the cylanders.

Your out of warrenty already? How many miles do you have? Any mods to your car?

Let me know answers to these questions, and we can go from there.
