Hi,
Just wondering if anyone else has had this problem. I have an 89 Regal with a 2.8 litre V6. Lately when cruising at 58-65 Km/h with an engine RPM of about 1800 my car stumbles slightly. Now this is only when I have the gas pushed down slightly to keep the car to speed. If I let it off or increase the speed and cruise a little faster at lower RPM the car rides smoothly. It's as if the engine is stalling and then catching itself causing surging in the wheels. I haven't heard the engine stall out during these periods and it dosn't backfire or anything like that. Any thoughts!
