  • You car has some miles on it...mine has 120k and needs a good service...it bounces when shifting from 2nd to 3rd (AT)...got it from a dealer a few months back..probably will have to change the transmission fluid (its brown according to mechanic who chekd it) and the timing belt..do u know how much they charge for changing the cv axle (left) - they put a remanufactured one and charged me 317 USD for it...felt kind of a lot...
    does anyone know which transmission fluid and brake oil forester 01 uses? does walmart sell it? or autoparts a better place to get such things...

    thanks
    have a grt drive..

    Congrats, you're now a member of the 1/4 million mile club.

    Do a compression test to see if the valves really are bad. I don't think that's very expensive.

    Part for my Forester are from the dealer or OEM of the internet. Walmart should have fluids, but I am partial to Pep Boys.

    I sent you post before I read your reply (my bad). How do I do the compression test? On my 85 Laser it was easy, the spark plugs stared me in the face when I opened the hood. These puppies are on the side and there is no clearance that I can see. Suggestions are certainly welcomed and encouraged

    Good point, access is very tight. You'll skin a couple of knuckles just to remove the spark plugs.

    These guys specialize in wrecked Subies, FWIW.

    I just bought a new Forester 2007 2.5 xt limited with turbo engine. It is the last one in the dealer. I found that there are black dust in the exhaust pipes, not as clean as my 2005 toyota matrix.

    Is it normal? How could I fix it?

    Thanks
    :confuse:

  • Don't worry about it. The new car has not been driven much, idled a lot, test driven around the block, etc. Probably never been warmed up enough for the ECU to get into the closed loop mode and give the engine the lean running mixture.

    I bought an engine from F&S, very very bad service. When I went to pick it up they gave me a runaround and had to make a copy of my lisc. for them at the local staples store.

    F&S only listed one 2000 Forester engine for $2,000. I sent them an email request anyway, maybe the have something cheaper.

    Someone replied that the valves hit each other rather than contacting the piston. It might be just one side I am dealing with. Hope springs eternal.

    Those are good points - thanks for taking the time to spell it all out! :)

    That's probably soot which means that your fuel isn't being burnt completely. This suggests that your oxygen mix is not optimal and you should have your O2 sensor checked.

  • He said the car was brand new. Maybe the car was started up and stopped a lot, moved around the dealers lot, taken on short test drives, etc. Maybe the engine was not up to operating temperature for most the time it was running, so the ECU was in open loop and the mixture was rich.

    Before messing with the new engine, he should wipe the soot out of the muffler tip to get a clean surface to view, and begin driving the car normally. He might not see any more soot.
  • paisanpaisan Posts: 21,181
    I agree, it's been idling around the parking lot for a few tanks of gas. It's probably running rich due to no full warm up cycles. Give it a few tanks of gas worth of normal driving and it'll be fine.

    -mike
  • But he should wipe the soot out of his pipe with gas. Otherwise it will remain, and he will not be able to see that future normal driving produces no more soot.
  • ateixeiraateixeira Posts: 72,587
    On short drives the exhaust does not reach full operating temps and the fuel and water vapors do not evaporate completely.

    Just take longer drives.
  • "... the fuel and water vapors do not evaporate completely. "

    Sounds like you are referring to the white vapor plume as moisture in the muffler comes out the cold tailpipe.
    I think the original poster was refering to black soot deposits in his tail pipe, which would be from a rich cold mixture.
    The soot was deposited during the time the new car was driving around the lot and on short test drives.
    Now that he owns the car and is driving it normally, the deposits should not occur again.
  • I have a Subaru Forester 2007 only for 6months with many many problems.THE MAIN THING IS THAT I CAN'T SWITCH ON THE ENGINE AT MORNING!!!!!!!!!!!!!!!!!!Is anybody know something to help me i' m lost!!!!!!!!
  • xwesxxwesx Fairbanks, AlaskaPosts: 8,508
    Please clarify. Does the engine crank but not start? Does nothing happen at all when you turn the key?

    Sounds like a warranty issue to me, but it might be something simple as well. We do need more details to help you, though.
  • The engine cranks,all the lights are turning on, but there is no sound of the motor.Finally i manage to switch it on by pushing the accellerator and at the same time i turn the key.Also when the engine finally works the rpm are close to 2600rpm.After 3min they fall to 900rpm and the motor "shakes".
    If you need more information please tell me and sorry for my english.
  • I have a 2001 Forester that has a CEL. I went through this a year or so ago, and tried to get a code reader to pull the code(s) myself. That's when I learned that not all readers work with Subarus. I had to sell the Innova Equus 3030 I bought, even though I sent it back to them to be reprogrammed for Subarus, because it just wouldn't work with mine.

    Anyone out there know of a reader/scanner that for sure will work with my car? I don't want to spend hundreds, but I'd like to do this myself if I can.
  • ateixeiraateixeira Posts: 72,587
    I bought a $99 Actron and it read and reset codes just fine. Worked on my 98 Forester and our 2002 Legacy.

    It also worked on a friend's Chevy Suburban, an older model.
  • paisanpaisan Posts: 21,181
    If it isn't working properly, perhaps you can try it on another Forester? I have seen where the ECU on the particular car was messed up and that caused the scanner not to read it properly.

    -mike
  • I *hope* this is the right forum to ask this...

    I have a '99 Forester with 180k miles on it. It's been working perfectly, then suddenly the other day these two things started happening:

    Thing 1: The engine revs at stops (in "drive" with my foot on the brake), as well as in "neutral" and "park". It revs between 200 and 1200 RPM. Up and down, up and down. This is at almost every stop light. About 1 in 10 stoplights, it behaves normally.

    Thing 2: The transmission is not shifting properly: it doesn''t want to shift up when it should. Eventually, it *does* shift up, but much later than it should. And it often shifts down when it should not.

    The repair place is not sure what the problem is: they''ve already swapped out the oxygen sensor to no avail.

    Any ideas, esteemed Subaru folk? Thanks in advance.

    Sounds like a trans issue. It could be a simple or not.

    -mike
  • Well, I'd think the same thing, but even in neutral the engine revs. (And when it does there's no "pull" on the car, so the trans is definitely disconnected.)

    But good idea, any others?
  • paisanpaisan Posts: 21,181
    It could be the TCU sending the incorrect signals to the ECU and that's why it may be reving in neutral as well. :(

    Speed sensor? That can affect the idle and driveability.
  • paisanpaisan Posts: 21,181
    I'm not sure of that. My dad's speedo is shot on his 95 Impreza and the only issue is that when you rev the car over 3k rpms when the AT is in 3rd or 4th gear it will cut fuel on him.

    My speed sensor went about three weeks ago. Symptoms were CEL, no speedometer, erratic idle, cooling fans were on all the time it was running and it was impossible to engage the clutch smoothly without slipping the clutch like crazy. As a friend said, it basically went into "limp home" mode.

    First problem in almost eight years with this car.
