Question about 1993 Subaru Legacy

1 Answer

My car was running fine, then i stopped at a stop

My car (93 subaru legacy) was running fine, then i stopped at a stop light and the engine started idling erratically, then it stablized but the check engine light has been on ever since. I checked the codes and icame up with: oxygen sensor circuit open. And: starter switch is either open or closed. is that enough data to go ahead and replace to O2 sensor?

1991 Subaru Legacy 2.2L not Turbo "Idle" very


i would check the idle air control solenoid first. simply unplug it then remove the unit and inspect the air passage for any blockage and carbon buildup. Clean it if its dirty then test it out. If the IAC is good then you should look at the throttle position sensor.

My 94 Sedan DeVille had the same problem. The car ran great but would stall whenever I stopped at a stop sign or traffic light. Turned out to the the TPS (Throttle Position Sensor). It monitors and controls the idle. What happens is the secondary idle (idle when the car is warm) is too low. Since all the controls for fuel mixture, idle etc are done electronically, they can't be manually adjusted. The TPS is the most likely cause of your issue. A diagnostic test (performed free at most chain auto parts stores) will be able to confirm this or lead you to another component. Best of luck to you!

93 subaru legacy starting problems


Probably a short or loose connection between battery and starter motor, or on either end of cables. Id look there before swapping out starter.On cold days you might put a heater under car for a few hours before using it,do this carefully as to avoid a car fire, or look into a block heater for your engine.
