2005 Saturn Ion 4 cyl Front Wheel Drive Automatic 55000 miles
Hello, engine light on, blinks when I drive, steady when I stop. Scanner shows misfires in clylinder 1 and 4. Replaced engine coils, spark plugs. Tested NOID, fine. Switched fuel injectors 1 and 2. Engine light still on, still misfires in cylinder 1 and 4. Car seems to run fine other than poor mileage (18 hwy); revving it while idling will almost cause it to stall, then seems to correct itself. I am going to try testing the O2 and mass air sensors, but wouldn't think either would effect only clylinders one and four. Any ideas? Thanks, Jeff
have the same problem?
