Question about 1990 Subaru Legacy
Its possible that your
crankcase is full of gass too, I suggest change oil and filter, also, if it wont
go over 40, the converter (catalytic) is probably damaged as well, raw
fuel in the exhaust will break up the cat. Oil change is imperitive as
too much liquid in the crankcase will destroy an engine in seconds. Can also be caused by the clogged converter, too much backpressure.
Get a vacuum gauge, hook into a manifold vacuum source. Increase RPM to 1500-200 and hold steady, if vacuum gauge falls, exhaust sytem has a restriction, the cat or muffler or a pipe has a broken chunk of the cat blocking it.
Hope helps; keep us updated.
