Customer Question

Shirleen. 2006 H3 rough idle. changed oil, spark plugs all 5 coils and now worse with check engine light on
JA: Thanks. Can you give me any more details about your issue?
Customer: was running rough and oil light started to randomly come on at 700 rpms. So decided to change oil 10W30 that didn't work light was constant so changed the sensor that seems to have corrected its self. It's been idling rough so changed the spark plugs and coil. Now check engine light is on and its really rough and sounds like its sputtering
