If you tried the coils and plugs already, how about Seafoam to clean the injectors? |
been trying all types of cleaners and stuff. used Techron twice and now i'm using Marvel's mystery oil. with the Techron, the problem goes away for the tank with the cleaner and comes back after the cleaner is done. The Marvel's has like 5 "servings", so to say, and so far so good, with a little bit of the issue on the middle. I'm fairly confident that the problem will come back once I stop using it tho, since it seems to come back every time I fill up for a small amount of time.
Possibly need to check for a vacuum leak next and might need to get walnut shell blasting. What I don't get is why it goes away with cleaners and comes back. That's why I'm suspicious of injectors but it seems that everyone thinks i'm wrong
