Question about Subaru GL

1 Answer

I have a 1986 Subaru GL 10 Turbo wagon and it loses power at higher RPM. It acts like it's not getting enough fuel/air. I replaced the fuel filter and still have this problem.

Start simple. Check that all of your spark plug wires are securely attached. Consider testing or replacing the coil pack. It can also be a bad MAP sensor.

Can you drive to a local auto parts store and get a free code reading? That might help give you an idea what is wrong.

Well this could be in your timing. As cars get some miles on them the timing chain stretches therefore causing you car to lose alot of power.So you may want to have your timing set on this car. Also I had a taurus that had a bad torque converter, and it lost alot of power on hills and under loads, also when i gunned the gas pedal. so try the timing first. Hopefully you dont have a bad head gasket or a cracked head these symptoms you are describing are all signs of head gaskets or blown heads

There has to be a fuse related to the power windows, check the owners manual. it may reside in a secondary panel in the engine compartment.

SOURCE: Where is the fuel pump located on a 1984 subaru Gl ?

I have a 1984 Gl Wagon 4WD; the fuel pump is located on the passenger side, on the frame rail under the back door, just in front of the rear wheel. It and the fuel filter are accessed by dropping the mounting plate that also serves as a protective plate. Again, this is the 4WD non-turbo EA81 engine GL Wagon; could be different on the 2WD version.

Before we do anything else lets do a fuel pressure check to make sure the pump is a-ok as well as the fuel pressure regulator. Your gonna need shop manual for this as well as a fuel pressure tester. If all checks out then move to the Turbo code.
Turbo code looks like the waste gate is stuck open and your not building the boost. Do a visual inspection look for any signs of overheating and bearing wear. Check or change oil as needed.
With regards to the Mass air flow I believe you have to replace it. Keep in mind this thing might be the root of you whole problem.
I strongly suggest you use the shop manual for the codes you got. it will make this repair a snap.

First try a new fuel filter and check your air filter. Sometimes the ignition relay on those is intermittent too. You may want to check the timing also. It is ok to ****** the timing a couple of degrees and see if it runs better. The turbos on those cars can have issues too. take care and good luck.

My 1988 gl 4 speed with carburator dies when put in nuetral just prior to a stop.


Way more info is needed. Check the fuel filter. Could be plugged just enough to starve at a low idle but gets enough when you have higher rpms. Does it sputter at an idle? Could be so many things, to electrical, including needing the carburetor rebuilt.

I need to know if my Catellitic converter is plugged or not


A plugged cat is most likely the problem. Also, about the rich exhaust fumes, you might not be getting the right mixture of air/gas making your vehicle sluggish. Check your air filter to make sure its not clogged..

Ack like it is running low on fuel while driving or stop


Crazybonezz, check your fuel pressure, should be 50 psi from the pump or 30 psi within the system 'loop'.
