Hy guys/gals, so i just bought a 1992 subaru awd 2.2 turbo sedan as a second car, the car has a really low idle like 500-800 almost every time i start it and feels like it wants to shut off, now mind you this car has 199,000 miles and i have no idea what th previous owner has taken cae of, could it be something as simple as a tune up? or what might i need to fix it?i also need to know what type of oil i should be putting in, thankyou
Hi doesnt sound like anything major as long as it doesnt smoke bad or knock from the engine, it sounds like a decent service would help, try replacing the air filter, fuel filter, give it a decent oil change ( i use castrol magnetec in my part of the world), give the idle air control valve a good clean with mass airflow cleaner or similar. If thats dirty it may fix your problem when cleaned. The hot idle should be approx 500rpm and cold should be approx 1000rpm hope this helps
SOURCE: I have a 1997 Subaru Legacy Outback AWD. The
when you replaced the plugs , was one of them (cylinder 1 ) dirty and fouled ?
I'm thinking that bad rings in cylinder would give you low compression , and eventualy cause the missfire by fouling up the plug.
There is an inexpensive product that will help with the compression by filling up scratches in the cylinder walls. It is called Restore , and it is one of the only products of its type that I have used , and feel actually works.
Unfortunately , if your rings are broken , or badly worn , nothing in a bottle will fix them.
If your car had a distributor cap and rotor , I would change them too.

Limited slip axles require in many cases the additive. It is ***** whale oil that is added to the required gear oil. Ck with Subaru is best. They sell it in the parts department and if capable you can add it yourself. or, have the dealer service your differential fluids. fluids
SOURCE: Stalls while driving. no good reason from
you need to have the engine coolant switch
checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the
computer will make it a rich or lean mixture to start the engine,if it tells the
computer that it is 75 degrees the computer will lean the mixture like starting
a car in the winter without a choke.

There is a differential pressure sensor mounted beside the 2wd fuse link with a couple of 5mm pressure lines going in each end. These lines connect to each turbo output. The two pressures acting on each side of this sensor produces a voltage read by the ecm which tells it the differential pressure between both turbo boosts during acceleration. Normally the primary turbo leads the boost and the secondary turbo plays catch up until the pressures are even then air valves get opened and shut to bring the second turbo compression in parallel with the first turbo. The two turbos simply act in sequence but function in parallel. Its just like having one big turbo but operating down two smaller paths.
The sensor measures the changing boost pressures as the second turbo rises to equal the first.
If the generated voltage is not what it expects it shows as a code 66. As you can start to see there could be many different reasons why there might be an imbalance in the two pressures.
It could be either turbo causing the imbalance or a faulty bypass valve or pressure relief valve or a number of other issues. It doesnt necessarily have to be a turbo or a solenoid which is faulty. All it means is that the pressure difference between the two boosts is wrong.
The real question is why is it wrong.
There is a lot you can do yourself to diagnose the cause. If you are able to study the manual which is available free off the internet (do a search for the link) then you will see that you can test many of the component parts quite easily at home and also temporarily replumb the turbos to bypass aspects of the system control to figure it out for yourself. To do this you will have to gain an understanding of how the twin turbo system works. However its not hard if youi strip away the complex jargon hiding simple functions.. There is a mystique of fear concerning working on these motors which is not justified.Just use common sense and logic.
Or you take it to a shop and pay someone else to do it for you.

I have the same problem!Running on three.I have checked compression,wires,plugs.Changed injecters,plugs.
3 mech.cant figuire it out???
