I have posted here before on the tuning forums, I have a 2010 SS with the 6manual, and the 6.2 I have a full ARH exhaust including cats. a CAI and a Dyno tune from JDP Motorsports. some time back I would notice a slight misfire, and it seemed to be at between 1k and 2k rpms while surface street driving. It has steadily gotten worse, the dealership can only show a random misfire, and does not set off any lights on the dash. I have changed the plugs, wires and cleaned the mass airflow sensor. Has anybody else had this problem and been able to track the issue down? the car runs perfectly except this low rpm issue and it does it at a steady speed in any town driving. While the car idles with the parking brake applied, every once in a while I can see the tach dip and pick up but not at a consistant rate, unsure if it may be related but just a symptom. Thanks, Ron Tilley
