I am getting an engine light since the work was done. once the computer is hook up it reads countless misfires on cylinder 3. This probem was not there before work was done and is pissing me off. I contacted the shop and he told me to gap plugs from .030 to .023 and this did not help. Can anyone offer suggestions to what it might be and how I can solve it.

 

stock gap is around .032 or so. That's where mine are gapped. Make sure they're all gapped the same, or at least near the same gap. If that doesn't work, perhaps you should switch injectors. If the problem moves to another injector, then you'll know that the problem is with the injector. Only other thing I could think of is perhaps the tune.
