Which ECU? The car has many. If you need a replacement, check the usual suspects like local wreckers, Ebay, or car-part.com can help you find a source for used parts.

thanks for your reply, however i dont need to know where to find another ECU, i meant where is the location of the ECU at in my car. Whichever ECU has the pin outs for o2 sensors and 02 sensor heaters wiring is the one i need

Thanks again
