I tried to adjust the ignition timing but can't get the ECU in base mode! Yes I tried to jump the little plug above the ECU and still no go! The engine runs very rough when cold but better when warmed up. I'm thinking the ECU is prolly only reading as a fully warmed up engine or something!!! I tried to read the fault codes by jumping the ECU plug but again no go. OH...it's a 93 del sol s...1.5 sohc non VTEC. Does anyone have any clues?

well the basics to reseting the ECU is warm engine up have the fan come on twice or so....

then turn car off reset ecu witht he jumper or pulling the batt cable

wait 30 seconds...

then take jumper out or reconnect batt cable

then start engine up and let idle for 10 minutes as ECU relearns engine... now it's reset
