Question about 1996 Subaru Legacy
Does not run rough prior to stalling, but just acts as if I turned the key to off, then starts right back up again. The ck.engine light came and Autozone code # P0100 and PO115. ..Also, If A/C is not running it does not stall...at least not yet.
The stalling problem could be caused by a faulty mass airflow sensor. That is the PO100 code. The other code is for the engine coolant temperature sensor. Go to the autozone website at autozone .com and register your vehicle. It's free and you will have access to an online repair manual. The procedures for testing the MAF sensor is outlined there. Hope this helps and you find a resolution to your problem. Best wishes.

You need to replace the mass airflow sensor. i had this just happen to me. you wil be better off getting one at a junkyard rather than buying it from like autozone or napa.

Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.
