my 2000 wrx did something weird the other day just after getting a turbo timer installed. i was taking off slowly from a stop sign bout 3k rpm and released clutch slowly, the car shuddered so i put the clutch back in and gave it higher revs around 4-4.5krpm and released the clutch slowly it then shuddered like it was going to stall, i put the clutch back in and tryed to take off again and was fine, i have been driving it for a few days whith no problems and no shuddering to speak of and then today it did the same thing except today it smelt like something was burning. just wondering if anyone else has experienced this?
