I recently posted a question about my 2004 Outback that emits a strange sound [like paper in a fan] when I am traveling on the freeway between the speed of 70-75 [only] upon acceleration. If I go above or below that speed range and/or remove my foot from the accelerator, the noise stops. It is, however, an intermittent noise which is frustrating in itself. Since my purchase of the vehicle in March 2006, I have taken it to the dealer 4 times for this problem -- the first 2 times they claimed that although they heard the noise that they could not duplicate for long enough to diagnosis. The second and third time they adjusted the heatshield, replaced an exhaust bracket and replaced one of my Catalytic Converters. All of this and the noise still continues. My car only has 33,000 miles. The truly unfortunate thing is that although the dealers cannot figure out what is wrong, they have continually assured me that they do not believe the problem to be serious. Although I believe Subaru makes a good product, I truly believe that my vehicle has a problem that could potentially cost me in the long run. Because of this I have hired an attorney to pursue my Lemon Law rights. I wish you the best of luck in finding the answer to your similar problem.

My wagon has 200 miles on it and have noticed when stopped and give it gas to move there is a slight hesitation as if the car might not be getting enough gas or wanting to stall but it's ever so slight I'm wondering if I should take it to the dealer. It's an auto non-turbo. Has anyone experienced this?
 
Thank you

Hey all .I got the ECM reflash because of the hesitation on acceleration .The car was still under warrenty so no pay from me . I have done some testing and have found that my car pings on shell gas. I now use the gas that WAWA sells and have not heard the pinging .I do try to run a can of seafoam every oil change.

Thanks, good luck with yours. Mine doesn't sound as severe. It definitely makes the noise only around 1800 rpm, but not when parked. It's interesting that you mention they adjusted the heat shield. That's kind of what I did, I bent it slightly in different spots to see if it would make a difference. Nothing changed. Both cases sound like resonance at that speed.

True, I may not buy premium each time as I fill at least twice a week since I use my car for field service. I wasn't going to bother trying premium since mid grade made no difference. I figured I'd try it after I saw your post. Sounds like a professional cleaning would be big bucks. At least a fill with premium is a 300+ mile fix. Maybe it's my imagination but it seems like there's very slight power increase as well. I just don't know how the engine would be effected over the long term by using premium intermittently.

I just got a used '05 outback. I have been experiencing the same exact thing!! I'm assuming the servicing on your outback is not fxing the problem. Did they tell you what is wrong? Is it covered under the warranty?
 
Any input would be appreciated.

The timing belt remove/replace is a 4.5 hour job. If your replacing the pump, it's a good idea to replace the belt (especially if your are near 105K or 210K miles).

Pinging is also called knock or pre-ignition. The fuel is igniting before it is supposed to. Knock can be caused be incorrect timing or carbon build-up in your cylinders.
 
If you are experiencing constant pinging you may consider changing your knock sensor. When engine knock is detected, the ECM retards timing (the spark happens a little later during the cycle) a bit to stop it.
 
I experienced ocassional knock in my '00 OBW at throttle tip-in from idle, but it'd only do it once. This is not a bad thing, as the ECM takes care of it. I did notice that I do have slightly improved milage and no knock when I use 88 octane fuel.

#6270 of 8644 hum when engine turned off (2002 Legacy L Wagon) by rdh3t

Jul 23, 2006 (7:53 pm)

Hi,
 
I have an automatic transmission 2002 Subaru Legacy L Wagon,in good shape, under 50,000 miles. Recently it has been making an odd humming sound when I shut the engine off. This is a low pitched sound, steady (not vibrating or oscillating), and it can last up to 45 seconds or so with the car shut off and key taken out, until it eventually fades off to silence. I've never heard anything like this before it started a week or so ago, and I haven't taken it for service or anything--I figured I'd start here. Anyone have any ideas?
 
Thanks,
 
Ryan

The service manual for 2000-2003 lists the code as follows:
P0171 : Fuel trim malfunction (A/F too lean) : <Ref. to EN(H4)-155 DTC P0171 — FUEL TRIM MALFUNCTION (A/F TOO LEAN) —, Diagnostic Procedure with Diagnostic Trouble Code (DTC) for MT Vehicles.>
 
There is no P0174 code in the manual or the H6 supplement.
