Question about 1986 Subaru XT

Open Question

Hard starts after sitting, occasoinal idle hunting

I have a 1986 subaru xt turbo i recently purchased. It has problems starting. It helps when i wiggle one of the fuel injectors. I can also hear the fuel pressure regulator "hissing" on and off while i do this. I try to start it when the hissing stops which seems to work. After starting it will die immediatly unless i give it gas for a long period, and then it will idle hunt or stay perfectly normal!

Previous owners seemed to think water had corroded the wires under passenger seat which was making it so the car car wouldn't start. Said whenever it rained car had problems ( I live in SEATTLE). Car had a lot of moisture inside, they did take out the passenger seat and mess with the wires when i bought it as well as wiggle the fuel injectors to get it started. They cleaned and or replaced sensors as well as new spark plug wires and battery.

Car runs great, but has a issue starting when it has been sitting for a few hours. The fuels injecton hoses do seem to be hard and kinked and fuel pressure regulator seems to be trying to compensate for loss of fuel pressure. I thought about replaceing o-rings and hoses for fuel injectors, but not sure as this is a "new" vehicle for me

SOURCE: Car Flooding-Not starting

I had the same symptoms. I had to count the correct number of teeth from the crankshaft pulley to the cam pulley marks.It is a different number of teeth to each pulley.It turns out that I was off by one or two teeth on one cam.

SOURCE: Cold Start Idle Issue

Problem might be the air control valve, it's located at the right side rear of intake manifold and has a hose going to the air intake duct from the air cleaner, as a test you might try pinching off that hose when the idle is a problem.

I have a 1987 Subaru gl-10 turbo 4wd wagon that recently started smoking when i get off the hwy, curious what could be the problem. Please help


Two things could be the problem. Seals within the turbo can wear and when pressure within the turbo lowers, as when you exit the freeway, the oil pressure pushes oil into the turbo either burning it in the combustion chambers or burning it in the hot exhaust stream. Also the valve seals can be worn and the same thing as the turbo seals happens

1991 Subaru Legacy 2.2L not Turbo "Idle" very


i would check the idle air control solenoid first. simply unplug it then remove the unit and inspect the air passage for any blockage and carbon buildup. Clean it if its dirty then test it out. If the IAC is good then you should look at the throttle position sensor.

'88 Subaru GL AWD Turbo, Shift on the fly wagon, that will sometimes start and sometimes not. There are also power surges. I put a new cap on her and new wires and was excited that she had more...


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.

Car not idleing, won't start when warm


If you have a stock carb those things have a million vacuum lines and if they are old and stiff and cracked that can also affect it. also look at your intake gasket and maybe replace it. My car had similar problems and i replaced the vacuum lines and intake gasket and it runs and idles great. good luck
