Question about 1993 Subaru Impreza

1 Answer

My 1993 Subaru Impreza intermittently stalls while stopped and sometimes appears to do so while driving.

The car has turned off while going about 30 mph and occasionally acts as if it is running out of gas (the rpms drop then rev back up again) when traveling at higher speeds even though it has plenty of fuel. While going downhill at steep inclines, the check engine light comes on, but then goes off when I press the gas. These problems seem to only occur when I'm not pressing on the gas or have just let go of the pedal.

SOURCE: Engine runs rough after about ten minutes /idles really low

Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

check the fuse for your ecu in the engine bay. Replace it and see if that works. See if you weld on a car without disconnecting the battery you send a current to your ecu that could fry it. Nissan thought this one out and put a fuse in front of it. LOL! but all cars have it too.

I'm guessing your mixture is too lean and it's possibly running a bit rough and there isn't enough fuel getting to the engine. A rich mixture is too much fuel, but that error is usually related to O2 sensors. It might be the O2, but 'trim malfunction,' you're looking at a vacuum leak. Check the oil separator valve then the throttle body gasket and then the intakes. Most likely a vacuum leak and the throttle body, oil separator and intake are the most likely. Run your hand around the bottom of the throttle body and oil separator, if it's greasy/oily there, there's a leak.

If there is no leak, test the MAF sensors...they might need cleaning, and in a worst case scenario, might need replacing.

Lots of things it could be. Egr valve sticking, a hose that came off, a bad sensor for airflow, or even throttle position sensor.

Intermittent nature seems to point to something sticky or loose.

Stalling problem with a 1993 subaru impreza


if the error code is saying bad cylinder id check it first, if it tells you which one take get a compression tester onto it, on all cylinders actually and check that they are all around the same mark. but even with a bad cylinder you should get some response, check the cable is still tight in the engine bay if not tighten it.

Subaru impreza uk model wrx stalls and low idle, hesition


try adjusting the throttle cable, its a case of loosening a nut, pulling the cable through a bit more and then tightening it back up, you find it on the right hand side of the engine block close to the exhaust manifold.
