Been getting a cylinder 1 misfire for a couple of months now. My mechanic has already did a complete tune up about 2 months ago, ran good for about 1 week, then light came on again. Still cylinder 1 misire- so he replaced cylinder 1 coil. Ran good again for about 1 week, then same light came on yet again. This time he took off fuel injector #1 and backflushed to remove any debris. Got it back less than a week ago, now light is on again....It seemd to come on when the car is sitting at idle. Or when in park and the engine is running. Getting really frustrated...The light will come on for a couple hours or a day, then it will go off for a couple of weeks, then the same thing will happen again. What might the problem be?
