sounds like a faulty ecu or memcal. If the engine light is on without errors it's a memcal or ecu problem and the car will be in limp home mode, generally will idle faster and be down alot of power, it's possible one of the pins on the memcals eprom has broken it's solder, I've seen one before like that
