Under what conditions does it overheat? Do a search for "head gasket" on this forum and see if the symptoms of bad ones seem familiar.

Please be sure to get the actual code(s) ("Pxxxx", where the x's are numerals), not the code definition(s).

Or the FPR (fuel pressure regulator) isn't getting proper vacuum applied.

This may be covered. See: http://www.endwrench.com/pdf/summer2003/FRONTSPR.PDF

We in the "colonies" sometimes forget that you guys "down under" get different models than we typically see here. So, does the car we're talking about have a turbo (twin?) with coil-on-plug ignition?

Hooray for easy!

Nice pictures -- did you compare them with the ones in the links in my previous post (#7) in this thread? The in-dash shots certainly look similar. The version of Compact Disk Database (CDDB 2578) matches the one used in certain Kenwood models. Perhaps you could contact Gracenote and ask them if there's a correlation. http://www.gracenote.com/ Beyond that, it's not likely that many of us on USMB have much experience with JDM nav systems. Good luck.

I may regret asking... ...but why do either of you favor a Fram filter (that's painted blue)? When the OEM ones were Tokyo Roki, I used only those. Once Subaru switched, so did I -- to Purolator Classic. So far, no problem (other than the cup-type filter wrench that fit the Tokyo Roki doesn't fit the Purolator). As to filters rusting through, I've had it happen to the external ATF filter on the 4EAT -- road salt will do that.

You're welcome. Sometimes it is that easy -- I hope it was this time.

That's very possible, the symptoms fit. EDIT: But do see http://www.ultimatesubaru.org/forum/showthread.php?t=108914

I may not apply in this case, but see: http://endwrench.com/images/pdfs/TurnSignals.pdf

If the two cylinders that cut out are paired 1&2 or 3&4, it's certainly possible that the igniter is failing when it gets hot. Once it acts up, a voltmeter in the hands of someone who really is an "electrical specialist" should be sufficient to determine if that or something related is the cause. On the other hand, if the problem cylinders aren't paired as I mentioned, which two are they?

If you decide to use resistance measurements as a means of checking the coil pack, be aware that: 1) A bad coil can sometimes check "good" if resistance is the only basis used. 2) There are sometimes errors in the factory manuals with respect to the coil testing procedure, and a good coil might seem to be bad based on that. If resistance readings don't match what the manual says, post what you got and we can probably tell you whether there's likely a real problem or not.

Indeed, or differential noise, transmission noise, axle noise, "etc." noise? Realistically, even with a good description, it would be difficult to tell you precisely how much longer it would be before a part failed and left you stranded (or worse).

Bare metal is the preferred surface. However, if the paint is free of wax and is clean, dry, and especially if sanded to provide some "tooth", the filler will stick quite well. But that still doesn't make it the best choice for attaching trim.

Oh, well if we want to do the job right, ... There are all kinds of adhesives, etc. (including double-sided tape, which for certain purposes is a simple solution) that 3M has for automotive applications.

Yes, Josh. For example, with ABS code 44 ("A combination of AT control abnormal") the first diagnostic step is to check whether an "AT model is installed on an MT model", and replace if it's the wrong one.

You could try a test batch, but that temperature is probably too low --read the directions. See http://www.roadsters.com/filler/ , a pretty good write-up where 64 degrees F is stated as minimum temp for curing.

You likely have an OEM Kenwood system. Does the following look familar? http://minkara.carview.co.jp/userid/261117/car/160672/1019101/note.aspx (You can use a web-based translator, but there isn't much more of a clue than the picture and the Kenwood link, which is dead.) Kenwood was an OEM supplier: http://www.cars101.com/subaru/navigation.html The Kenwood firmware comes on a DVD, and I believe it's needed to change both the OSD language and GPS map. If you don't have an English copy of the owner's manual, you might be able to get the info for free. From http://techinfo.subaru.com/html/index.jsp : "OWNERS MANUALS: If you are a current Subaru owner, and you are looking for an Owners Manual, please go directly to https://my.subaru.com. You will be able to view your specific Owners Manual free of charge with your free registration to the site." I hope that helps.

If considering torque bind, see this thread, in particular my post #8: http://www.ultimatesubaru.org/forum/showthread.php?t=108790

How have you determined that the problem is related to "the speed sensor"? If by trouble code, which code was retrieved? The '99 does have known VSS-related problems, sometimes manifesting as speedometer issues. However, "delayed engagement"/slipping is also common. See: http://www.ultimatesubaru.org/forum/showthread.php?t=87708

The code 25 indicates a problem with the rear right wheel sensor - "Open circuit or input voltage too high". The other code likely relates to having the wrong ABS control module for an MT. (The TCU and ABS units normally "talk" to each other, and probably the ABS noticed the difference.)

Yes, there's a difference in the teeth between the 304 and 307 belts. See: http://www.ultimatesubaru.org/forum/showthread.php?t=93767 For application, see: http://www.gatesoe.com/documents/Gates%20Import%20Applications_web.pdf

The engine emissions control section of the manual probably has more detail. The purge solenoid is under the intake manifold, the rest are usually back near the canister.

There are three solenoid valves. I mentioned the purge control because the hood label shows it. As to their locations... ...download the last manual on the page that naru linked to and look at the On-Board Diagnostics section for P0440.
