I have a 2005 Mitsubishi Eclipse GTS V6 3.0L with 54K on it. I don't drive it during the winter it sits in my parents barn. I just took it out yesterday and when I started it the check engine light came on. I had started it 2 weeks prior to that and let it run for about an hour and no check engine light came on. I went to Autozone where they plugged my car in and it came back with Misfire Cylinder 3. They told me it probably needs plugs and wires. The car isnt running any differently then it did when I drove it last year. It still takes right off doesnt make any werid noises no engine skip no nothing. What could be causeing it to read misfire cylinder 3. Is it possible that it just had bad fuel go through the system from sitting and to try and put some fuel injector cleaner through it.
