I inadvertently left the ignition on while cleaning the car, and after 18 hours it was seriously dead. Got it started with a jump (yes red to red, black to black) which did take some cranking and fussing.
Since then it is hard to start, idling way low (loping between almost zero and 250 rpm), stumbles, feels like it's hovering on the edge of a stall in traffic, and hesitates when driving. We live in Kailua-Kona village, a no highway beach town, so all subsequent trips have been short, slow, and in traffic. I've driven it on sport mode and kept the rpms up in the high threes and low fours a couple of trips, and I've opend the gas ca and resecured it.
Has it forgotten how to Subaru? I'm thiking the computer needs to be retrained? Best way? Highway trip, reprogram, has something been damaged? :-(
