Lots of things. You have not given enough information to answer the question. First please describe what you mean by "acceleration problems".
could be the blower motor, a fuse, or a bad wire.
Subaru 2.5 liter engine has a problem with head gaskets. If you have not had your head gaskets replaced, that is the first thing I would suspect.
Love.
I'm having the same issue, did you ever find an answer to this?
Subaru sucks. why the hell would you want a Subaru, especially the cheapest Subaru cause they all blow.
plugged fuel filter is the cheap and easy fix. the expensive and difficult answer is the catalytic converter is shot. with my luck, it's the cat.
No. Oil circulation has nothing to do with acceleration. A fuel filter change on the other hand may help. Things that cause poor acceleration include clogged fuel filter, clogged air filter, need of a tune up, some electrical problems or a clogged catilytic convertor.
The left rear corner of the head was known to leak on those years (mostly 2000-2002). Facory head gaskets were problomatic. Many were warranty.
Yes timing can delay your acceleration
The Code 45 you get in Subaru is as a result of the sensor which will cause the fuel cut.
If an alternator is going bad it can cause a rough idle in a 1993 Subaru Legacy. Cold temperatures in the winter can also cause a rough idle in the Subaru Legacy.
