No there is not a check engine light on but a few months ago it came on. I took it to auto zone they gave me two slips of paper with this on it:
fuel trim bank two condition
the ecm has detedted a rich or lean air fule ration
condition on engine bank two
if bank one and two are set together suspect fuel condition or maf sensor fault
igition misfire condition ( personaly i dont think this is it becasue the car starts right up after a stall)
fuel injector problem (I dont think this is it either becasue it runs perfect well driving on the highway, or cruising)
engine mechanical condition ( I dont think this is it either becasue the engine is still farily new)
Now I had two receipts this was the first one.
The second one i lost but it mentioned something pointing to the o2 sensor.
