Hey bretheren. Went for a cruise with some Ferrari buddies and had to cut it short becuase of a CEL 5/8. Car went to intermittant Limp mode but I got her home. Pulled the codes and got a 4121 (Cat code). Hmmm, no slow down light before CEL. Figured I'd swap sides for ECU test. Cleared all codes. Now I got a 1111 5/8 (Hot Wire MAF). Performed a master ECU reboot, cleared all codes again, now everything is fine...no more CEL. Took her for a quick and hard spin...still fine. Today went for a 100 mile melow ride, no CEL. I figure everything is OK and the indication was a loose connection, bad gulp of fuel, or something. Am I missing anything? Do I have something getting ready to bite me?
