My car set a code 51 today while shutting off at 65 mph. I stopped and cranked it back up and the engine light flickered on and off as I was keeping the idle up and car running rough. I shut it down and disconnect orange wire and changed chip. Car ran OK going home. This has happened twice now in the past three months. Last time the car ran extremely rich as I limped home. I changed the chip and the car was fine until today. I have not had either chip diagnosed yet. Is this a problem in the ECM or a chip problem or an ecm causing the chips to fail. The car also popped at 65 mph and my car has never done any popping before.
Thanks for any help resolving this problem.
