So the system has been reset and the cars does run better however a new problem has come up. When idling in traffic or at a stop light, the CE light comes on. Had the code red and come up with the random misfire. The cars feels to run well..
Could this be that the car has 195k mile on the ignition coils or could this be a result of a low current and the battery needing to be changed.
What is the best way to diagnose which could could be failing?
Thanks
