Question about 1997 Subaru Legacy

1 Answer

Acceleration issue I get the issue where if i were to stomp on the gas it just refuses to go past ~3k rpm. It doesnt always have that problem but it's getting increasingly more annoying. Replaced the O2 sensor and there's a leak in my exhaust seal on the farmost rear one (the last one before the end of the exhaust...the one with the spring screws) but I dont think that would cause the problem...would it? Oh and I also swapped out the intake with a different one hoping it would fix it. I replaced the tranny filter and fluid.

    Checked the codes with a taskmaster and the only code that comes up is one about the knock sensor...doesnt say if it's bad it just comes up. It also told us that the 02 sensor was bad which is why we replaced it. This whole engine was replaced just within the last month due to some airhead using it to dragrace and blew the heads.

    I have not replaced the fuel filter due to us thinking it was the transmission. We thought that since it automatically shifts at 3k rpm (automatic of course) we thought it was a tranny issue. I can try a fuel filter swap but if that was bad would it still work some days and not work others?

    Also if it helps...a friend of mine suggested I check the transmission shift sensor and try and get that replaced...what do u think?

Do you have any engine codes? It may be throttle position senso. It may also be good idea to buy new fuel filter.
Also you may want to get a multi-meter and check your fuel pump relay.
If you have a tester, you should also check fuel pressure.
If you have a check engine light on, you should have the codes read because it will pinpoint exact problem

I would consider changing the vehicle speed sensor. When they go bad, they can really throw out a lot of bad data to the computer, resulting in unexpected behavior like you're experiencing. They're only around $20-$25. I hope this helps! :)

You will need a computer to accurately read the signals you are getting from the sensors in the engine bay, but my guess is that the MAF sensor may be acting up.

One thing you should get checked is the oil pressure.You could have an oil pump that is going out or getting weak.Also depending on how regular you are with your oil changes it is possible that you could have a sticky lifter.The oil pressure at idle should be 4 psi and 25-80 psi at 3k rpm.If it is less than 4 psi at idle do not do the 3k rpm.This is check with a warm engine.(normal operating temp).Hope this helps.Good luck.

Poor acceleration on 850 GLT 5-speed

check the voltage output on the o2 sensor and the wires and plugs.the air flow meter or the coolant temperature sensor could also be an issue.
