Engine Misfire Help
Just Returned From Having Wifes 07 Coupe Serviced.
It Had A Misfire That Was Not Setting Any Codes And Was All Over The Place. Had Rear Serviced Also. Tech Could Not Find Cause Of Misfire. As My Car Was Being Worked On Another 07 Came Into The Shop With The Same Misfire. Gm Tech Line Was Aware But Unable To Help With A Fix Still Have Misfire Can Feel It Just Touching Car. 07 Auto 1lt Mont Red Chrome Wheels 8800 Miles. They Did Clean The Injectors. I Run 93 Octane Bp Or Chevron Buy From Same Places Always They Checked Fuel For Bad Fuel. I Have 2 Other 07's 6mn They Don't Have The Misfire.

I just had mine in for a bad misfire. Turned out to be just a loose spark plug wire. I think it probably was somewhat loose since I bought the car and only now after 13000 miles it finally got so bad it threw a Check Engine code.

IT IS MISFIRING ON ALL CYLINDERS ON THE TECHSCAN TOOL YOU CAN WATCH IT. FRIEND SAID TO DISCONNECT ACC DRIVE BELT TO SEE IF THIS HELPED NOTHING SEEMED TO EFFECT THE MISFIRE.
