Question Asked: Rough Idle
July 01, 2009, 03:27 PM
Read forums, tried disconnecting MAFS, O2 and TPI sensors. No Luck. I ran concentrated injector cleaner through gas... Worked for 2 weeks! Problem returned.. Tried same treatment... no luck this time! Thing runs like a champ when driving / accelerating. AutoZone's reader couldn't establish communications with my ECM. Tried two different Autozones... same problem.. Rotor, cap and plugs were replaced 12,000 miles ago.. The intermittent symptoms are driving me crazy! Once, I tapped on the Mass airflow sensor... Fixed it for about 4 days... What am I missing??
