Engine / boost problems.

[Guest]

Hi everyone, iv got a 94 rs legacy sedan thats given me nothing but trouble since iv owned it but anyway its running ok but it wont boost at all and ocassionally it surges as if low on gas. It builds pressure from vacum to 0.lb but wont go any higher and when I put my foot down it throws a CEL and goes into limp mode. Can anyone give me an idea of what I should be looking at. Any help would be greatly appreciated.

Also it has been leaking power steering fluid quite rapidly.

Hey bro, mines doing the same sort of thing, its the same car and sane year. Have you had any luck fixing it?

Check to see what code its throwing first. It sounds it's either a big leak past the compressor wheel (unlikely because it would run crap on idle due to it probably getting unmetered air), the waste gate actuator is open slightly all the time or there is a problem with your map sensor.

Check all the boost lines to the map sensor and waste gate actuator. Also check that the waste arm? (I'm not sure if this is what it is called) is still attached to the physical part of the gate in the exhaust.

I would definitely check that code first though.
