Hello together! I have had a 91′ 2.2 legacy with automatic transmission for a few years now. the only thing that really bothers me about the vehicle, are problems that sometimes occur in the empty run in the warm run phase (even if the engine is still warm…): first, the check engine does not go out – the engine does not look at it and the engine does not run “round” as if it were running on one or two cylinders only. he then has a whole lot of time until after some time (usually a few days) ) starts normal again and also the control light immediately goes out. the motor then sounds like an old diesel from a tractor and if you don’t give enough gas, he dies immediately. hopefully someone can give me a tip…
