Their rep even made a point of letting me know that my warranty was no longer covered "because of the years not the mileage". They looked at the car and told me that my #3 cylinder was misfiring and that a coil needed to be replaced and I should have my 100,000 mile tune up done now to change the spark plugs in order to fix the problem. I went back to the dealership and was told that it was just a coincidence that this happened after having it worked on by them, even though the car was running perfectly before that. As soon as I drove away the car was running rough, idling hard, and kept acting as if it was going to stall on me. I took my Cobalt in to the Chevy dealership in Surprise, AZ this morning for a routine oil change. But the problem is a sign that something is definitely wrong with the electric system on the car. Thank O'Riellys for the lifetime warranty because I don't have much money into this repair. And so far the problem has been solved for the longest time. Finally the last time I replaced the coils I also bought a new Ignition Control Module. Until it happened 2 more times! I have had 4 new ignition coils in this car, and the problem always came back. The ignition coil has a lifetime warranty so I brought it back to O'Riellys and exchanged it for another one. ![]() The new ignition coil fixed the problem! The car ran fine for about a year then it did the same thing, randomly misfiring and throwing the code with the flashing check engine light. Fuel pressure was good, so we went bought a new ignition coil set and installed it (a very easy install on this car) ![]() We changed the spark plugs (as it was about 105k miles by this point) but that didn't help. I limped it to a buddies house and read the code: Random Cylinder misfires. This happened on and off and I could never get it to do it during a routine maintenance to prove to the mechanic I wasn't crazy.įinally the engine started running like complete sh*t, throwing a code and flashing the check engine light. The engine started sputtering and even dying at low RPM's around 80k miles (like when braking at a red light or stop sign, as the RPM's dipped it would sputter and sometimes die). I owned my 2006 Cobalt since the winter of 2008 with less than 30k miles on it. There are many other comments about the misfiring cylinders and rough running engine on these Cobalts.
