misfire issue
ok so I have a question for everyone, I have had my car at the dealership more than a few times. I had the #5 injector go out, dumped so much fuel in the engine that they had to replace the injector, spark plug, oil, all O2 sensors and the catalytic converter. Since then I have had issues with it runnning, I get a surge that happens between 1500 and 2000 rpm but no codes. I took it to the dealership to have them look into and they "couldn't duplicate" the problem so I drove it for about a month longer with it still having this problem. Took it back last monday and the mechanic rode along with me and he saw the problem. Told me on wednesday that there was a misfire in the #5 cylinder, funny how its the same cylinder, today they call me and tell me that they didn't replace anything. "The problem is that I buy my gas from racetrack and the additives are causing the #5 cylinder misfire." They want me to get my gas from Gate instead because that will fix the #5 cylinder misfire. Now to me, if it was the gas I was using I would get a misfire in more than just the #5 cylinder. Am I wrong in assuming this?????
