if the KE control unit is the thing near the battery i already tried swapping it with another one i had lying around, when unplugged the engine would drop down to very low rpm but the same backfiring chugging etc. was still happening though i think bad control unit would cause similar symptoms, im still planning to try changing the coil tomorrow though... haasman i know what your saying,the only thing thats good about wild goose chase repairs is that after you finally find out whats wrong youve replaced so many things that the car runs much better but your wallet is
