Last week I took my car in to get several oil leaks fixed, including a gasket they had to take the entire thing apart for, and spent 15 hours on. 3 days after it was fixed, I start driving and the car starts jerking and the check engine light comes on and starts blinking- I slowed down, but even at idle it was running roughly, still jerking, etc. It finally settled out but the light remained on. Today, I turn it on and nothing. Smooth running and no light. I find it something of a coincidence this happens three days after the engine was just partly taken apart. I have previously replaced spark plugs and ignition coils, and the symptoms reminded me of the spark plugs, like a fuel injection issue, but I don't know enough to really know. Could this have something to do with them putting it back together improperly?

take it back and have them re check there work with your concerns. the code will be stored so they can view the code. if it returned to normal, then then it is intermittent. Roy
