This is a new development, the intermittant noise started about a month ago, the idle issue started after I cleaned up some vaccume lines and replaced the coolant temp sensor, though I would think if that work was related to the idle issue that cylinders 1,3 would have issues too. I'm going to check plug wires and timing later today and see if it slipped a tooth. It's a newer timing belt with new idle pullys and tensioner as well, all was replaced 10k miles ago.

I check there often and haven't seen any oil leaks yet (they are new seals as the head gaskets and all other gaskets have recently been replaced). I will check again tomorrow during the daylight to see if something is going on. Also noticed an intermittent lifter noise on that side of the engine, the two may be related I'm thinking now.

***SOLVED*** Original message below: ----------------------------------------------- Finally got my computer to throw some pending codes. After a drive on the freeway, idle is rough when I give ever so slight throttle to the car, such as when attempting to park. Anything between 800-1200 rpm is really rough. I held it at that rpm to get the ecu to throw codes, P0302, and P0304, Cylinder 2 and 4 misfire detected. I would think if it's a cam issue it would be rough throughout the rpm range. Coil issue maybe?

***Update*** Well, no improvements on fuel economy so far. Over the last two days however the car started to stutter and almost stall while idling in gear. Especially for a brief period after starting to accellerate from stop. Put the car in park and did a very light engine rev, it's having the same problem, at about 1200rpms it gets very rough. After that it smooths out again. I'm starting to wonder if my coil pack is bad. No engine codes yet despite that bad running. I bought a live scanner tool, It calculated mpg based on MAF and vehicle speed. Around town driving it calculates about 22-24mpg, freeway it calculates about 27-30mpg. Averages around 23mpg with stopping, accellerating and what not. So something is still causing it to dump to much fuel in as far as I can tell. Anyway, whatever is wrong with it, was also a problem on my 2001 Outback, it too had issues with idle when light throttle was applied with a load. Maybe not the same root cause, but it's almost identical in symptoms now.

We were very careful. :-) We did take a straight edge to the engine block and heads and everything looked good. Didn't have anything machined. Headgaskets are working as far as coolant and oil goes, so I don't think it's an issue. At anyrate, I do drive very light on th gas pedal, if I really push it (no heavy accel at all on the entire tank of gas) I can squeeze about 21mpg out of a full tank. That includes keeping the speed under 65mph, etc. I just replaced the coolant temp sensor, and took the car out to get it topped off on gas (it was at 1 quarter). The idle and acceleration is already feeling better than it did before today's work. We'll see how this tank of gas goes and I'll report back. Old coolant temp sensor was very corroded. Also found that the little Y plastic fitting for the PVC plumbing (one hose to the air intanke, other to the pvc valve) had so much oil hardened dirt in it that one of the fittings was completly blocked. Cleaned the heck out of all that too while I was at it.

Knock sensor is new, OEM. Forgot to add that to the list of new stuffs. I do know one of the front axles clicks sometimes, and I have records that it was done at a none subaru repair shop, so probably aftermarket. When I'm bored I'll get an OEM axle and replace it. I'm assuming they arn't any different to do than the ea81 series subarus were. Anyway picked up a new coolant temp sensor, I'll probably install it tomorrow or Thursday, will report back once I've gone through a full tank of gas on the new sensor.
-
That makes total sense! I wasn't sure if they were seperate for the gauge and ecu or not. I know where the ecu one is because we forgot to plug it in initially when we got done with the headgaskets. I'll try a new one of those and see what happens. I will report back with info and if that solved the problem.

Replaced front O2 sensor with a bosch. Plugs are NGK. Idle is rough when the car is stopped and in gear at times, smooths out when I put it in neutral. For some reason the extra load of the transmission makes it rough. (not the brake booster as it does it even when using the parking brake to hold the car in place while in drive.) When the car is at full operating temp the rough idle isn't as common. Mostly freeway 60-70mph, rpm's vary from 2500-2800 rpms depending on what range of speed I am driving on the freeway. Only about 20 miles of around town driving per tank of gas, rest is on the freeway (180-220 miles or so). We actually did not remove the valves or lifters at all, to avoid getting them mixed up or back in the wrong spots. Compression, valve clearance have not been checked. That seems like a lot of work to get 3-4mpg back. If that's really the "average" for that car on the highway, I'm kind of bummed. Maybe I'll try an early 90 ej22 long block swap when I get bored. I'm pretty sure it's not driving style, as I said, the 2001 outback got 25-28mpg on the freeway when I drove it, my old 86 XT turbo did about 32mpg average driving on the same commute route. Given how unfimuliar I am with fuel injection tuning I was hoping that maybe there was something minor I missed that could cause a rich fuel mixture. If not, then I guess it is what it is.

I've done a lot of searching but really haven't found much information. It appears most solutions to the fuel economy question has been that it's just normal after age. So, I have a 1998 Forester S, EJ25D with the auto transmission with the clock at 234k miles. The car gets about 20mpg on the highway, around 14-16mpg around town. It's only about 1-3mph better than my old 6.9L Chrysler. The previous owner is a family friend so when he tells me it averaged 24-26mpg before it broke I believe him. Bought the car for cheap because headgaskets were blown (combustion chamber to coolant passage). With help from friends I replaced the headgaskets and all the associated gaskets with it. I suspect something may have been missed, or possibly done wrong that could have comprimise the fuel economy. So anyway, here's what I have replaced, checked etc: Torque bind - was repaired Spark plugs, wires, pcv valve, timing belt, timing belt pullys (tension and idlers), tires, front O2 sensor, fuel filter and air filter replaced. I've cleaned the MAF with MAF cleaner and ran seafoam in the gas tank. Replaced cracked and broken vacuum/crank ventalator hoses and checked for vacuum leaks. No engine check light or codes. Does anyone know of anything else that I can check before spending hundreds on more parts? or to find out if I need to buy more parts? I'm kind of suprised that even though it's a smaller lighter car than the 2001 Outback I used to have, it does worse on gas, even with the same sized engine. I'm wondering if maybe the cat is gummed up from when the car had blown head gaskets. Any ideas would be great to hear, thanks!

It was an honer knowing Ed, a truely decent human. Condolences to his family and all who were close to him. Like many here and elsewhere, he's helped me out many a time without ever asking for anything in return, back to the days that I was still a teenager and complete stranger to him.

Best place for auto glass replacement for 1986 XT
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I'm going to go back up to Arlington either today or tomorrow to take another stab at it. I have a couple of spackle knifes, and more wire to tackle it with. -
86 Turbo XT 4wd re-assembly, stuck help!
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Nope, different wire, that one is already hooked up. This wire is about 4 inches long and it comes out of the same group of wires next to the distributor as the 2 wires that hook up to the ign coil (from the engine side) -
Best place for auto glass replacement for 1986 XT
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
yeah, started on the window at the arlington pick n pull, but only got one side undone, the corners are really hard to cut out. Broke the wire I was using several times. (Windsheild place provided the wire for me). I have a place willing to install it that also has a front window in stock. I'm going to try calling junk yards now to see if I can find one that has an XT that can pull the glass for me. If no luck there I might have to just scrap the car after-all. -

Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Does this place have a name? Still on the hunt and haven't found anyone yet that has rear glass. I attempted to pull my own out of a pick n pull but wasn't very successful, they crushed the car before I could finish. -
86 Turbo XT 4wd re-assembly, stuck help!
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
It's a 1986, sorry forgot to add that. -
86 Turbo XT 4wd re-assembly, stuck help!
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Thank you for your help, I have to figure out how to get the usmb to notify me people have replied. lol. Bracket instructions make sense and help a lot, i'll get that installed, starter was already in, so that makes since why I didn't see where it goes. Knock sensor is already plugged in. This wire is at the other end (drivers side) by the coil, it's a spade plastic clip (normal subaru electrical plugs) type connector (black and yellow stripe if I remember right) separate from the two coil wires but it comes out of the same spot of the harness, and is about the same length of wire as the coil wires. The other harness I pulled out has the same wires (identical). I replaced it because the knock sensor plug on the old harness was busted. -
I tried searching and it was about as useful as a paper weight. I was wondering if anyone that knows or has an ea82 turbo engine could tell me more about where the wires coming off of the distributor plug into? I have 2 wires that go to the coil, and a third single wire that I can't figure out where it goes, it's short, only reaches as far as the two wires that go to the distributor reach. Any ideas? Also the battery wires going to the starter motor have a metal bracket attached to them, I can't figure out where that bracket is supposed to attach either. These are my only two mysteries so far putting this car back together. Thank you for any help!

Hello, In the process of restoring my 1986 XT turbo back to it's original glory, I'm trying to find a company that can come out and install both a front and rear windshield in the car. So far I've called Allstar auto glass and Safelite and neither of them can get rear window glass anymore. Does anyone here know of any good auto glass repair companies that still take care of the odd cars suchs as this one? I apologise if this has been asked before, search function hasn't been much help to me for some reason.

Poor 1986 XT turbo (sad story)
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
The Arlington Pick n Pull just received an 86 XT, I figured, why not, made the drive up north to check it out with a pleasant surprise. It was the same color, and it was a turbo. The body is straight too! Snagged the moon roof, hood, and trunk with trunk seal, and back seat, all in good shape. Carpet and front seats were trashed. It is a 2wd, struts and rear discs are still there. Other than what I took, the front hubs were missing and the dash had been torn apart, that was it. Pics of the big score are below! -

Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I have not... also, as I mentioned at the beginning of this thread, I've been away from the car stuff, including this board for the better half of the last 3 years. I'll be doing some forum searching in a bit regarding XT stuff and see what's happened in the last 3 years in the community. -
Poor 1986 XT turbo (sad story)
Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Hood isn't a must of course, the non-turbo hood on the car right now is actually not damaged. Moonroof was ran over by a truck, it's as far as I can tell beyond repair. I'll get pictures of it soon. -

Mr. Carb replied to Mr. Carb's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Good to know, does it still have the moon roof? Also, does it have a turbo hood? If I'm restoring this, which I think I will, I will first see if I can get the engine running for starters, then go from there. It had an overheating problem, the kind where the fan wouldn't turn on when it's supposed to, even though the fan works, and the radiator switch works, whatever is in between didn't. After replacing the head gaskets, never could get it to run right again. -

Finding parts is my struggle right now. Pick n Pull was my source, but I've been checking all summer and haven't seen any XT's come in at all at the local one.
