Okay, maybe I am. I have big trust issues when something goes wrong with my car. Here's the story: I have a 2001 Forester S (automatic) with 55K. Couple of weekends ago I came back from a relatively short trip, car drove fine. Came home and about an hour later went to the store. On the way to the store I noticed a weird bogging-hesitation sensation. Thought maybe it was my shoes or something under gas pedal. On the way home from the store, noticed extreme bogging. While going uphill to my house, I had to really put my foot on the gas pedal. I barely made it up my driveway--had to put it in first. Next day, took it around the block, only slight bogging. Did not drive it until I took it to my Subie dealer a week later. On the way there, (about 20 miles), car was okay as long as tach was above 2,000 rpms. At the one stoplight I hit, car was idling low and temp gauge went back down to cold (this was after 14 miles). (No overheating issues at all and no check engine light.) I kept one foot on brake and the other on gas to keep the car going at the stoplight. Subie dealer diagnosed bad gas and changed fuel filter and put dry gas in it. They couldn't find anything wrong with thermostat. They ran car, kept it overnight and drove it again in morning. Said car was fine. I tooled around town down there and it seemed okay. So this is my big paranoid question: I feel/think that there is a slight hesitation when tranny is shifting from 2nd to 3rd. Is car too young to have tranny issues? Is this a cold problem, (although I noticed it after driving around for 10 minutes)? Should I wait until I've gone through a whole new tank of good gas? Would bad gas have caused these issues? HELP
