#134 of 148 '03 Legasy P0507 by fordwrench Sep 06, 2009 (4:25 pm)
My '03 Legasy has set a P0507. I have already cleaned the throttle body and IAC. The CEL is on intermitantly now. I have never seen the idle speed hang too high. I priced an IAC at $300 ouch! Is there anything else that will set that code? I have checked for vacuum leaks, none, fuel trims are at 0 long and short, and I've checked for throttle cable misadjustment all ok. The car runs perfect and only has 63000 miles.It is a manual trans car by the way.

Replying to: simonbones (Jul 08, 2009 1:59 pm) I have gotten this code - well so many times that I cannot count - over the past 5 to 7 years on my 2001 Legacy wagon. I am not willing to spend the money to get a new Cat system, so I tried putting in a fuel line cleaner in. About a half a tank later it went off. I went to a different gas station and it was fine, but when I went back to the place that I filled up prior to the first time the light was back on after a quarter of a tank same code. So it seems to me, atleast with my car, it is quality of fuel.

#137 of 148 1998 legacy and it random blinking lights by mgc98legacy Oct 02, 2009 (6:40 pm)
new to the forum, anyways i've got a 2.5 GT 1998 legacy that just recently began having the hazard lights, the dashboard, radio all start blinking when the car is off. I noticed that while this off the same clicking noise it makes off is also occuring while the car is running. the check engine light had been on, i had recently changed all the spark plugs, spark plug wire, and cooling system. The car runs fine with the check engine light on. I feel this is something to do with another aspect of the electronics system. any ideas??? i pulled the battery and put her to sleep for the night. thanks for any help!

Replying to: mgc98legacy (Oct 02, 2009 6:40 pm) I wonder if it could be an alarm or remote keyless system malfunction? Change the battery on the key fob, perhaps?

Replying to: bobny57 (Jun 03, 2009 11:44 am) Bobny57   If you've still got te 2005 XT - you need to be very careful about the turbo. I have a 2005 Outback XT with 67K. I've been very good about changing oil and my turbo has now blown out. It's been in the shop for the last few days and I don't have a complete diagnosis yet, but I'm sure that it will be very expensive. Apparently there is a mesh screen in the banjo bolt that's in the turbo clogs and starves the engine of oil and bang - you've got a dead turbo on your hands. Looks like Subaru knows about the problem but hasn't been informing it's owners. Maybe this screen can be cleaned - if so it will save you much hassle. Just wanted you to be aware. I'll probably be posting more about my situation soon. Replies to this message: ateixeira (Oct 27, 2009 12:41 pm) cindy47 (Nov 25, 2009 8:14 am) ateixeira (Nov 25, 2009 9:05 am)

#142 of 148 CEL 2003 Outback by cansub Nov 04, 2009 (4:00 pm)
This car has about 50,000 miles and I have owned it since new and had it dealer maintained. The CEL came on recently, and apart from now running rough for a few minutes when starting from cold it runs reasonably well. I take it into the dealer on Nov. 6, and having read all the horror stories about trial and error part replacement in order to get the light turned off, does anyone have advice as to how I can avoid this happening to me.   Any ideas as to what may be the problem.

Replying to: cansub (Nov 04, 2009 4:00 pm) if it's cat/con before 100,000 Subaru should replace it. Mine blew at 102,000 and they wouldn't touch it. My closest Subaru dealer is a snake so that's the last place I'll ever take it or buy from.
