Hello, just got back from the dealer after a check engine light came up. He said i was getting code P0304. He charged me 170$ to clean injectors. Check engine light came back this morning, so i went back to dealer. He replaced injector #4, but now he says that it is misfire randomly between cylinder #4, 5 and 6. The check engine light is no longer there, but dealer doesnt like the fact that the misfiring is still occuring...have to go back on monday. Any thoughts?? Im also making dealer reimburse me the 170$ for the injector cleaning...dont know if he will

Did they actually clean them or just add something to the gas tank? I guessing a fuel additive.

I've gotten the code once or twice never did anything about it. Cleared it with the predator. I'm not sure how that cleaner will work? Maybe it could be something else. Maybe you need some new plugs if multiple cylinders are misfiring? How old are the spark plugs? Are you running at least 91 octane fuel?

A Predator is a good starting point to begin modding.
