Hi all, I just became the owner of a 1984 Subaru GL Sedan with a ea81 engine. The engine was "supposedly" rebuilt before I got it, but hard to tell. It is very greasy. I thought they usually steam clean an engine before they install it. Anyway, When I first got it, it would not idle below 2000 RPM. I let it warm up, thinking engine computer would kick the idle down. Nothing. I then picked up a Chilton manual, and it said there is an idle mixture screw. Looked at the screw, preset at factory, no way to change. this is a Carter-weber single barrel with Electric choke. I am suspecting a vaccum leak? Some of the hoses have been removed that plug into the air filter housing, and have been plugged. Is there any other way to adjust Idle speed? Next thing: I will be driving along at 60 MPH. The temp gauge will rise steadily to red zone, and the gas gets sucked down. Also, when the car is warming up, or I am driving, the ECM light will come on and stay on. Is this indicating a problem with the Cat Converter? Could it be plugged up? This car was owned by pot heads, so it wasn't taken care of. The front end on the drivers side is smashed in from a car wreck, and it shoved the whole front end over to the passenger side. Luckily it didnt mess up the strut towers, but headlights are off, so is bumper. Can this be fixed? Is unibody fixable? The car has a lot of pep, and has good excelleration. I would really like to keep it, I plan on doing some performance things to it, if I can iron out the problems. Sorry for the long winded tale, any help will be greatly appreciated. :santa: Merry Christmas!
