yea that definetely helps my question...im most likely getting the sensor wednesday and replacing it by the weekend. BUT the thing is the car has been running funny before that as far as the motor knocking and RPM surging when car is cold from 800-1200 rpm...the check engine light sensor just started saturday after replacing radiator and removing thermostat, so i can see how replacing the sensor would solve the starting rough or stalling part of it. hope for the best..
