my service engine light was on for about 3 days. today It went off. I got a 2K2SE AUTo and when I was in D gear, it idled rough. But this problem has gone away and the car is running fine now. The light went off also. Should I go to the dealer anyways to get it checked?

 

Probably... Most likely it depends on whether or not you need the piece of mind as to whether or not everything is ok. If the problem has gone away, I bet the dealer won't find anythng wrong.

 

Thats what i was thinking. probably the dealer will say everything is fine. I am wondering if there is a bad coil. Seems a lot of 2K2 models have this problem.
