I've done a search on here and freshalloy and can't find anything that will help me. Ecu is throwing code 21. Power Transistor. I've already changed the distributor on the car (bought straight from Nissan dealership). Car is a 98 S14 5sp. Car runs fine and does not idle rough. Starts everytime it is fired, so i'm stumped. Car is basically stock cept for a HKS exhaust. Need to get this fixed so I can pass smog! If any one can help please do!
