My pathfinder 1999 just burned my ECU. Had, Knock sensor code, P0443 (Evaporative.....) and misfire P0300. I though it was time for it to go. Well, got an used ECU, got it programed and about 5 minutes running, another burned ECU. No codes now. Did not get the famous P0505 code or TPS code or anything besides what's been mentioned above.. Wondering if anybody can help by getting me get in track to find what's causing the burning of perfectly ECU's as the same card got burned and they had been checked prior to installation.
thanks
