I had some missing and shaking of the motor. Filled up the truck and put in injector cleaner. Drove 100 miles and it got better. The computer said it had a cylinder 5 missfire. Is it possible that the injector cleaner is cleaning the injector and maybe fine after I run this tank through?? Should I put in another bottle of cleaner next time I fill up??
I tried 2 doses of HSS and it didn't help. I don't have contribution codes, but I get really bad cold starts which are injector stiction related.
