Hard to answer, did you ask around? How about internet. I still have the original package stating: "AmPro compact offset oxygen sensor wrench, T75518; 22 mm" Good luck.

Can you explain? I don't understand.

I didn't ask that question but guessed why it was asked very easily.

To be positive, you have to invest in OBD2 scanner and learn how to use it.

Are these all hwy miles? If so, this translates to like ~125000 city miles, that is also impressive.

Why would someone revive this after a year?

O2 sensors are cheap enough to swap them for diagnostic purpose. It is a wear and tear item after all.

On a final note, subaru is probably not the engine to learn how to do it. Too costly to fix stupic mistakes. Ask someone to help you and show you the ropes.

My 00 (same engine) is noisy, last time I checked, 75 db at idle. It sounds more like noisy injectors though. Also, don't forget that this engine is prone to develop piston slap, so that may be what you hear too.

Not different from a regular plug job, except that you have to remove battery, washer fluid tank, and intake ductwork to get access the the plugs. It took me a couple of hours of slow paced work. I put double platinums plugs with antisiese, so I would not have to redo it in mere 30,000 miles. Rubber hose is great to screw plugs in without crossthreading.

Vaccum leak would be likely with these problems. He is clearly running lean and the fuel system cannot compensate any longer. But, it could be easly be O2 sensor, MAF sensor, fuel filter, fuel pump, or even ECU problem. The original poster needs either learn how to troubleshoot the problem correctly or pay someone to do it (I would not recommend a dealer though).

Mr Fish, Your plug advice is useless for newer subarus as they have "waste spark ignition" and will eat through 2 of your single platinum plugs in no time. If one wants to use platinum, only double platinum is an option on subaru. NGK calls them laser platinum ($7-12 a piece). I just switched to laser platinum as they last 60000 miles and plugs are pain to change in subaru. As for your PCV advice, you want us to vent the toxic fumes to outside air?

LOL! So much for the heated tranny overheating discussion. If you tow, the wear and tear is going to be greater, period. So, the story from your mechanic might be true. I would be especially woried about cluch. This is why some people prefer auto for towing (with cooler of course).

Hard to say, but you can always measure the fuel presure as part of your troubleshooting. The above comment is correct, MAF gets easly dirty in MAF-equipped engines. Some Subs are MAP-equiped though. Did you look into dirty fuel filter, dirty throttle, dirty injectors?

Off topic: What fiats did you own? I don't see any in US anymore. I used to own/drive fiats, but it was in europe. Most were sad POS, yet some bulletproof, like UNO with FIRE engine.

This is a good description indeed. Wouldn't you think that some of this should be covered in the car manual? Most subaru drivers will not come here for advice on winter driving and be surprised that the car fishtailes or slides. Some would learn the quirks of AWD driving the hard way. Many people have false expectations about AWD. Hey, I did myself.

LOL, joke, right?

I have never seen that claim before. Can you reference that? I would expect the oposite, used oil may be thinner due to VII brakedown. Oil thickening due to oxidation and ultimately sludging would not happen before several K miles or couple of years.

You are all correct except that 2000+ uses A/F ratio sensor and not an everage, cheap O2 sensor. The good news is that front OEM is like $60 and rear OEM is more like $160 though.

I don't know 05 but the uhall hitch I have for my 00 Legacy is the best thing i've seen. Well hidden under the bumper und practicaly invisible from a normal height. Cheap too. Obviously I drive without receiver ball when I don't tow, unlike most bozos in pickup tracks around here.

I think you hit it right on the nail with the explanation. I learned that hard way when my wife drove and she suddenly lifted gas pedal on an icy curve. As soon as she did it we went in a 180 degree spin and our legacy landed in a deep shoulder. Clearly an user error, but most people driving AWD don't know that AWD behaves differently or has irs quirks. Hey, when ConsumerReport evaluated legacy back in 2000, they gave lower score on emergency handling due to "fish tailing" in obstacle course.

IMHO, these are the most recurrent issues, HG and torque binds; recent examples here: 99 Subaru Blown Head Gasket 2000 OBW Head Gasket Leak 93 Legacy & Torque Bind

I I were you I would not make any assumptions but made sure the car is tuned up by the book. Who knows, maybe fuel filter is clogged up and never changed. Subarus are very sensitive to user errors (read neglect). I would not take any chances.

I can only tell you that in my subaru, with hwy driving in mild/hot climate, the temp is exactly 180F. The highest I have seen was 212F with prolonged idling. I never checked in freezing conditions, though. However, 2/3 of temp gauge sounds high to me. Normally, should be 1/3 to 1/2 of the scale. Though Saab may have different gauges? BTW, is it more cost effective to buy subaru rebadged as saab? Can you service it at subaru dealer? (:-)

The only problem is there is no transfer case. Did you mean front differential? Now, you know that the 99 2.5 DOHC is a ticking bomb, right?
