An additional common problem is that the black computer chip assembly inside of the distributor, may be about to go out entirely. Always have a spare distributor that works. The plugs getting worn down, will cause occasional missing and help blow out the alternator prematurely. The ground wire to body, can get hot, brittle and lose conductivity resulting in lack of power to the engine and accessories. A bad Oxygen sensor in the exhaust can set that light off.

The wire that goes into the nut attachment on the back side of the alternator, can get hot, brittle and lose conductivity before it breaks altogether. That used to give me that code. Otherwise, do a search of my posts on here where I list about a dozen different electrical problems that cause engine failure and/or failure to start.

Felpro is what everybody is using these days, because you don't have to keep retorquing the head bolts.

On my 86T, that is one of two identical vacuum/suction devices that keep all of the other suction dependent devices functioning, such as the 4WD shifter as I recall. If your 4WD shifter goes out, this is the first thing that you check. The two vacuum/ suction devices are located directly behind the Turbo air filter assembly, on the engine right side of the car. They can become unplugged and therefore stop your 4WD from shifting, or you can break off that male tube extension that the hose is pushed over. I had one go out completely at maybe 350,000 miles. All of the suction gismos on top of the engine, are connected to that sucker. The distributor advance suction hose is independent of this system because it is a variable suction to the distributor.

That alternator likely has all kinds of internal corrosion and it does not take much to affect voltage output. Get a new one.

Single defective items that can by themselves keep the engine from starting and has put thousands of Subarus in junk yards: 1. the black fusible link is the main engine but any of them can start to break or get hard and brittle, causing intermittent and then total failure. 2. the thing a ma jig that bolts to the body, directly behind the fusible link box, that had one wire to the coil and the long black wire running to left side engine attachment next to the battery, where the ground wire attaches. The thing a ma jig also keeps static off of your radio and right before it blows, you get a lot of radio static. 3. the main engine ground wire get brittle and loses most of it's ability to conduct electricity and ground out the engine, at it's attachment to the frame. This single defect will cause the engine to run poorly when you operate any other accessory on the vehicle. For instance, you can almost kill the engine by operating your electric windows, if you have them. THIS IS THE MOST PROBABLE CAUSE OF YOUR PROGRESSIVE FAILURE. These wires may not last more that 250,000 miles. 4. a loose wire inside of the distributor cap 5. the short wire between the Positive battery terminal and the fusible link box, gets hard at the terminal end, brittle and loses most if not all of it's ability to conduct electricity, causing poor performance before a total engine failure. You splice in a new lead to the battery terminal, by splaying both ends of the two wire ends that you are joining, in order to get the maximum about of contact surface. 6. the distributor electronics just suddenly went out. 7. the hot wire that runs into the back of the alternator, gets brittle, hard and breaks, causing the engine to perform poorly before it suddenly fails. 8. bad plugs will cause your alternator to fail prematurely. Some plugs require replacement every 15,000 miles. 9. coil failure or corrosion inside of the lead wire from the coil to the distributor. 10. Bonus: a failure of the replaceable round switch below the dash board, to the left of the steering column, will cause the interior fan to suddenly fail, especially if you had just been running it at it's maximum speed. There are about 5 of these identical switches below that dash in the same location so you are going to have to get a known good switch and plug it into each switch socket, one at a time, before you find the burned out one. There may be black discoloration on the burned out one.

Actually not. They come with a strong tint and that tint is useless for the prevention of the slideable cover from heating up and radiating that heat down on top of your head.

You need to have a backup distributor because they "go" without warning, and then you are going to need a tow back home, because the Subaru dealer won't be open or won't fix it for a reasonable price.

Les Schwab carries winter and summer 13" tires.

If you have a GL10 or some other model with a sunroof, I found that the sliding cover is painted black on top that absorbs a lot of heat from the sun and then radiates it into the cabin. And the bottom of the cover is the hottest part of the ceiling on a sunny day. So the solution to that is to apply aluminum faced tape to the top side and you will be amazed in the results. Then the bottom of the cover is the coolest part of the cabin ceiling and on hot days you don't get that heat buildup radiating down on top of your head. Which is particularly annoying when it is over 100 degrees and your A/C does not work.

Try John's Subaru in Laurelwood, Oregon

My guess is the $20 Exhaust Gas Temperature sensor that screws into the catalytic converter. Your welcome in advance.

John's Subaru in Laurelwood Oregon has parts that you cannot buy anywhere.

It probably needs rebuilding at this age. Which is a new circular seal ring, a new boot and they through in a metal ring to seat the boot inside of the caliper.

A bad exhaust gas temperature sensor will cause all of your bad engine problems, which you do not appear to have changed. About $20. It screws into the side of your catalytic converter coming out of your turbo.

3 idlers plus 2 belts in a kit are available on EBAY for the best price that I could find.

I believe that the engine runs off the battery during ignition and switches to the alternator once the key returns to the run position. So you might check the alternator wiring for it being in place, and then the alternator. There are also three wires that go bad in the same area. The ground wire gets hard and goes bad where it is bolted into the chassis, just in front of the battery, causing the engine to run rough with headlights on or working any other accessory. The wire that comes off of the bottom of the hot battery terminal wire and goes to the fusible link box, gets hard and loses it's ability to conduct electricity. The wire that is bolted into the back of the alternator also gets hard and loses it's ability to conduct electricity, causing the engine to kill.

As I recall, once you remove the boot to uncover the ball bearing assembly, there is a circular wire clip that wraps around everything, that you pop out in order to disassemble it enough for the ball bearings to fall out onto your work table.

I have had this happen a number of times on my 1986 GL10. There are about 5 silver 1" diameter x 1 1/2 long gismos that I believe are switches, under the dash board and just left of the steering wheel column. They plug in and pull out. If you take a look at each one by unplugging it, you may find one that overheated and is slightly dis-colored. That's the one that is fried. You can swap it out with another one that is working but obviously, you will want to get a good one so that everything is working. They last a long time, so used ones are Okay to plug in.

And the inner joint pin only come out one direction, and then only goes back in in the opposite direction. A taper around the hole is at the exit and entrance end.

I put the nut back on and this put a 2x4 flat over the nut and hit the 2x4 with a heavy hammer. Obviously, the inner connection to the transmission, should already have been disconnected.

If the genuine subaru mechanic did not smear brake fluid on the rubber cv boots, then how else are those boots going to both crack and require replacement at the exact same time. As I recall, they did it too my vehicle twice.

Look for rust in the frame around the bottom of the windshield, once you remove it. You may need body work.
