Random RPM Loss, Car Almost Dies.
i have a 2006 cobalt ss, the car just died on me 2 weeks ago, it would start but immediately die again so i had it towed to the shop, the tow truck punctured my oil pan on the way, they checked the codes at the time and there were a few but they were all over the place and had nothign to do with each other, so they cleared the codes and once the oil pan was repaired, they started the car and it started up just fine like nothing was ever wrong, no codes came up and it ran fine fer almost a week but now a week later randomly i loose rpm, almost think its gunna just die like it did before but then it comes right back up, sometimes it will sputter and almost die a few times in a row. no codes, no lights come on. any help would be much appreciated. Thanks.
