I have an 89, 7mge. So, the only strange thing my car is doing is idling a little high (1100), otherwise I have yet to notice any other symptoms. The check light doesnt come on when the car is started, only when i begin to accelerate hard. The only code it throws is a code 11. The only information i can find is that its thrown due to a momentary interruption of the power supply to ecu. what could this mean? what could be other symptoms? what should I look for? what are the possible causes? what could I do to fix it?
