How hard was it to just do a search within a specific forum to find what you need? If you have a Tribeca and have a question on the NAV, it seemed pretty easy before just to go to the Tribeca forum, search on NAV, and read the posts. This seems to be a major step backwards for the forums.

Will you describe the problem a little more? When does it tend to happen... after several hours of being parked, or just a few minutes after?
I may be able to help you out on this one with some specifics.....
Here goes: For acronis, I think it might be a mass airflow sensor failure - meaning it has just went kaput altogether. The part itself is about $350-400 new. I suggest this because my problem, reasonably isolated to the MAS (and has not happened again since it was replaced), showed the following symptoms: The car would stall occasionally while at an idle - sometimes in the driveway or a parking lot, sometimes at an intersection. When attempting to restart, the car would usually not start. I could crank it until the battery died, and nada. But, wait 5 minutes and try again. Sometimes it would start, sometimes not. If not, wait another 5 then try again... repeat until successful. The longest it ever took me was 25 minutes, or 6 attempts. The non-start problem was something different from the MAS, though. It persisted after the stalling problem was (assumedly) fixed and only disappeared after replacing the knock, crank, and camshaft sensors - though an actual failure by any of them was never recorded by a non-start event, so I do not know (with certainty) which was the actual source of the problem. I am inclined to think it was the camshaft sensor.
Basically, though, my understanding about these sensors is thus (perhaps Steve, Craig, or someone more knowledgable about them can chime in if I am off base here!): The timing sensors tell the car when to send spark to the plugs, so if there is a failure there, then no spark or mis-timed spark means no firing. For the MAS, it feeds back information about quantity of air/oxygen entering the intake, so misinformation or no information feedback will cause the car to run too rich or lean. At idle, this effect is most pronounced and can cause the car to stall.
There could be other problems here, like a fuel injection issue or feedback from one of the other systems, but I would think that if spark, fuel, and air were in the cylinders at the same time, it would at least stumble when trying to start. An easy way to check for fuel is to pull the fuel line off the output of the fuel filter and turn the ignition to the "on" position. Route the line to a container, of course, and have a helper to witness, as that fuel pump is going to spray fuel quickly and you only want to turn it on for a moment before shutting off. If there is no fuel, you know the issue is with the fuel pump!
Those are my thoughts, hopefully you can dig through them and find something helpful.

Good description of parts and function. The only thing I would add is that some systems (depending on year, sophistication) also have a separate idle-air circuit. When the throttle plate is fully closed (idle), this separate pathway meters a fixed amount of air around the MAS/MAP sensor, and sends an estimate of flow to the ECM, with additional feedback from the cat O2 sensor to fine tune it. I guess they figure that the MAS/MAP sensor accuracy at very low CFM is questionable, so provide a different measurement method.
My 1999 Subaru Legacy has us stumped. We get a hesitation during acceleration, sometimes a violent shake in 1st gear. (The car has yet to die during one of these episodes.) The hesitation is variable, ie there is no correlation between the hesitation and the time of day, weather, ect. The only correlation is that it generally runs fine when we take it our mechanic. The most frequent code we get is for the oxygen sensor. We have replaced the 1) throttle position sensor, 2) idle control valve, and 3) oxygen sensor.
Any thoughts??
Thanks
Why would they have discontinued red? Who can I e-mail, call, beg, threaten, whatever to get it in red?
Now I'm wondering do I need to wait until the 2008s to see if they bring red back. I would rather not, because my poor 90 Legacy needs a break from long trips. I do have someone looking for a new 06 Legacy GT for me in red.
Any assistance would be greatly appreciated.
If you haven't already, try new spark plugs and spark plug wires. If they are original they are overdue for replacement. Beyond that, look at the ignition coil ($80 or so). Also try a fuel system cleaner like Techron.

This is actually one of the primary reasons I am steering away from Subaru for our next purchase. My wife is dead-set on one though, so who knows. Even though I am the one paying for it and working on it, I seem to have very little sway on her opinion. :sick:
I'm wondering if others have felt the hesitation and if it's just a function of the six cylinder. This car had very few miles on it.
Thanks for sharing. I'm not going to pay $30K for a car that can be dangerous. Sad because I LOVE my '95 Legacy. Funny you should say that about your Jetta. I just sold my Saab, which I loved, hoping to save $$ down the road. I'm going to test drive the Acura tomorrow. Then on to the Camry and Avalon which from what I've read on these forums are having the same tranny issues. I wonder if there really is something in the self-training transmission.
or maybe you need to try another dealer or specialist tranny place because there may well be a problem your delaer is clueless about. don't necessarily take the delaers word as gospel truth, some of them are clueless
If your primary use of the car is traveling in unknown territory (delivery, sales, lots of travel), then it might be for you. Otherwise I'd spend the $$ on other features.
My Outback without the NAV system has a nice covered storage area for sunglasses and pack of gum..

I have such a list for speed traps and red light cameras, so it warns me as I approach those.
Wish I had it sooner - my wife got a speeding ticket on Bradley Blvd right where it crosses over I-495 in MD, and nowadays we get the warning and remember to slow down.
Cool stuff. I paid $404 but they are *much* cheaper now. Think I saw one for $260, new too.

PS Make sure you get the latest maps, v8 is the latest.
We are now using our 5th new starter (all on warranty!), but by now even our mechanic is convinced it is not cause by the starter
It seems that every time a new starter was put in, the car was less prone to this problem, but soon it would start again and get progressively worse. Could it be related to the ECM, which is being reset after the battery gets disconnected? But the wiring schedules I have suggest it is not involved in the starter wiring at all.
Some other, probably unrelated problems we have after replacing the knock sensor:
- somewhat rough idle, but only when in Drive, not when in Park/Neutral,
- strong gas smell when driving small distances.
Any suggestions appreciated, because we are getting worried about getting stranded at some point...
I had the exact same problem on my farm truck. It turned out to be a lose wire terminal on the starter relay.

They usually call it just Outback, but some times you see Legacy Outback.
Oddly, when Subaru announces sales, they include Outback sales in the total Legacy sales. But not the other way around. Weird.

Here's what I ~ know
According to Subaru, the front stock component speakers have a bass response down to 75hz but they sound much lower. Also, I've been told that the stock speakers are 8ohm, so just replacing the speakers (no amp) is not a good idea as aftermarket options are always 4ohms. According to Subaru rep, the rear door speakers are not even coaxials. Also, heater controls are integrated with the HU, so full aftermarket swap is problematic. Front doors are limited in space, so mounting depth is an issue with many component speakers.
I'm worried that if I add line-level converter, amp, and four speakers, I'll actually lose bass response as the stock speakers already have pretty good low range, and many of the shallower component speakers lack good bass response. Alternatively, I could add a 4-channel amp to power front components, bridge 2 channels for sub, and then keep crappy rear door speakers running off the HU power, but would have a big sub to conceal.
Just curious what types of aftermarket systems folks have done, and how it turned out. Sounds like the stock subwoofer upgrade fits under the driver's seat, which would leave room under the passenger seat for a smallish amp??? Anybody have any experience with the factory sub upgrade?
Any thoughts/corrections would be appreciated.
By the way, since I sell them, I drive the LLBean 3.0 a lot, and have never experienced any hesitation. I drive them hard as well as "normally". The only "hesitation" is from the XT due to turbo lag. That is annoying. Yes, I can be very critical, and yes, I own a Legacy sedan paid for with my own $$. I used to have a company demo, but no more. I still love the Legacy, even when I make the payments.

Makes me wonder what happened - did the older car break down irreparably just before they finished shooting the movie or something? Why would they need to have two different cars? :-)

Want to buy a used Outback with approx. 45-85k miles (at best a manual or is there anything suggesting that this is a bad idea ?)
What are the typical things I have to pay attention too, when buying an Outback of that age ?
thanks
Joe - don't want to spend money on a :lemon:

00-01 models still had the older head gasket design, so I would focus on 02 and newer at least.
Besides that, there's no major pattern of big problems with those, they're quite reliable actually.

Both trannies are fine, just test the clutch for clutch chatter. If it's smooth you're fine. If it shakes when cold, well, it doesn't usually affect longevity, but I'm not sure you want a clutch that isn't smooth.

I guess they changed filming location and did not find exact the same car.

Meh, I'd use Subaru Bucks if I ever had to do that.

78000 miles (conservatively driven) and the head gasket has failed. There are lot of postings on this problem which appears at mileages well below 100,000. I find this shocking.
I can't believe that Subaru's reputation has not been demolished by their unwillingness to address this widespread problem.
