Would alternator/battery problems result in running rough ie missing? I didn't check the car Day 1 when the battery was dead, I just assumed I had left a door ajar and a light wore down the battery but I really don't know. Day 2 the car seemed to start OK but it ran rough, the battery held enough charge after the short run on Day 1 to start Day 2 and enough from Day 2 to start once on Day 3 (Day 3 being today). I might not be remembering correctly but I am pretty certain the rough running began immediately after the dead battery on Day 1, (It ran fine the day before!)

My 91 Legacy is stranded 4 hrs from home. I'm counting on the USMB to help me out! Here's the symptoms: Day 1 - Battery dead in morning, boost to start. Drive about 20 minutes to store, hmm seems to be missing, running rough. Day 2 - Starts OK, drove about 1 hour, still running rough, missing, won't develop much power but still moves along at highway speeds. Day 3 - Starts OK, runs very rough, missing, runs for 2 minutes, then I shut it down. Tried to start againg 3 hrs later, battery dead? Tried boosting, won't start. Engine spins fine with boost but it won't start. Any hints/clues?? ECU ??? Maybe a fuel issue? I'm lost.
