Question about 1991 Subaru Legacy
Look in to the throttle body right before the throttle plate and spray carb cleaner in the throttle body .
clean all the black carbon out .this carbon builds up around the throttle plate and causes the idle to drop cause it cant breath.use super unleaded to prevent this from building up again.
hope this helps.

Hi there think I can help, had the same issue with my 1991 Liberty 2.2 turned out the airflow meter was the problem. There is a metal sheild inside the top cover which covers the circuit board but very close, when it got hot under the bonnet the metal sheild warped enough to short out and stop the engine. It is well sealed but I pulled off the square black top lifted up the sheild and stuck insulating tape to the underside and stuck it back together. Might be worth trying a donar part if you can but sounds just like the prob I had.
