i have a 97 subaru outback ,"check engine" light is on( been on for a few months), sluggish on acceleration, (no power),then stalls at low RPM,
when accelerating the car starts to loose power, struggles to keep up, then
stalls at low RPM, this is an intermittent problem, mostly on hot days, engine
temp normal, recently changed the tranny fluid and filter, and upstream OBD
sensor, can you tell me what is going on here.
