Check engine light comes on, car runs rough when radiator cooling fan kicks on. Anyone have any new ideas?
Now the radiator fan stays on all the time, along with the "check engine light." Even when the car is stone cold. Is there a sensor or switch I can replace to correct this?
I can't check the trouble codes because the "check engine light" stays on as soon as the ignition is on.
