It detects the status of the throttle (if it is closed, the cruising speed or intense accelerations). With this information, the ECU can calculate the air/fuel mixture and the optimal ignition point to achieve the highest efficiency and performance achievable for such state. It is known as TPS (Throttle Position Sensor).
Starts fine usually. Dies intermittently redstarts sometimes not others could be cold or hot stopped or on highway. No codes found instrument lights don’t come on when this happens it is just like engine disappeared. Sometimes when wet outside starts and runs less than two minutes dies and won’t restart until possibly the next day. New tps cleaned iac same map used ecm.
