Hmmm... not sure what it means exactly, but the timing is fully computer-controlled. I wonder if it was just a hiccup? Perhaps reset the error code and see if it pops up again soon. If so, probably something to take to a shop for diagnosis. Be sure to log this event (when it happened, driving conditions, etc), though, in case it ends up being a sporadic problem.

OK here is some info I was given today. There are 2 hydrolic adjusters one on each cylinder head, They have Banjo bolts with screens in them that will get cloged or even fall apart. The adjusters work by oil flowing thru them . As you get on the gas the oil pressure boost and it advances the timing for performance. Was told to replace them and to replace the Bango bolts in the turbo line just in case. Not sure where the bango bols are in the turbo oil line so any help there would be great. Have the parts on order at my local subaru dealer. .. Oh yeah and when I bought the car they said to use coventional motor oil but now are saying to use synthetic with this motor.

Synthetic has much better wear properties than conventional, so yes, I agree that synthetic is preferable.

95 subaru legacy CEL problem by 95sl

i have a 95 subaru legacy and the CEL came on and i went to get it scanned and it came bac as P1104 which is engine torque control signal circuit malfunction. When i had it scanned the guy told me he never heard of it and he owned a subaru himself. He told me to bring it into the dealer. Well i called around to local mechanics first before i would bring it in to the dealer and all the places i called have never heard of this problem either but they all said it probably had something to do with my transmisson. I was wondering if someone out there had this same problem or had a solution to this problem.

This is exactly what I just experienced and our mileage is close. What happened? They originally replaced my oil sensor, but the check engine light came on again and now the dealer says I need a new turbo and catalytic converter to the tune of $5,000. I have had all the O2 sensor problems and many of the others discussed on this forum.

Outback XT Performance by Roobar

We have 2005 and 2008 Outback XT's with auto transmissions. The 2008 has a lurching shift between gears 2 and 3. The 2008 acceleration is also more sluggish that that of the 2005, even with the auto transmission in Sport Sharp mode. Has anyone else experienced similar symptoms with the 2008?

Mine is a 2006 GT-Turbo with 5sp Manual. I ONLY get the CEL when I travel between my two homes. One home is at 7000' in a cold climate and the other is at about 3000' in the desert. Usually, I get the light when I go from the cold to hot climates. Every time I take it to the dealer, I'm told its a loose gas-cap.
 
I NEVER fail to tighten the gas-cap and I am especially aware of that now. I suspect that the problem is caused either by the change in temperature or the change in altitude (pressure). I always buy gas at the half-way point between the two homes.
 
I had a Forester with the same problem and then I had a Baja that never flashed a CEL.... ever.
 
Comments? Ideas?

Check Engine Light by 2009buyer
Feb 16, 2009 (11:23 pm)

I have a 1996 Subaru Legacy Wagon. I bought it from a private party when it had 11,000 miles on it. Not long after I bought it, the check engine light came on. Twice when this happened took to the dealer, they said nothing was wrong turned it off. They never said it was a known problem. Living in Oregon, it was not a problem as there were no emission problems. Now in California, just the fact that the light is seen as on manually, they fail your smog. No emission problems, car problems of any kind. The print out mentions a Knock Sensor. Had it replaced, drove it about 100 miles, had it smogged, now the light is on again. I have two years to do something about this. I love the car, but the only alternative is to sell for scrap in two years. This just not seem right that you would be forced to junk a car that has an engine that is so quite when idling, you can't tell it is on, no emissions, etc.
 
Would Subaru have a fix for this? One mechanic said it needs a new computer, about $1500. Another said it has nothing to do with the computer or catalytic converter. Any ideas?

Not that this is a solution, but you should seriously consider purchasing a scanner for the car. That way, when the light illuminates, you can read out and reset the codes yourself. This does two things: 1, you know what codes are tripping and how often, and 2, if something else goes wrong, you will not be in the dark about it (once the light is on, an infinite number of additional codes could crop up and you would have no idea).
 
Also, it would alleviate the issue of occasional codes causing a fail when having the test performed.
