A known misfire? I don't know that it has a misfire so I guess not. Today I put a new maf, air filter, cleaned tb, and did the idle relearn. Went on a drive and right when I was ready to declare it fixed, it started doing it again. However I think I learned something new. It is totally related to engine temp. It's cooler today...70f. Where do y'all think the temp gauge should read? When I'm out on country roads and the gauge is a hair below half it idles fine. When I get in town the temp gauge goes to half...perfectly horizontal. There's a slight shudder when the fan kicks on and it starts misbehaving. So it started dieing in town. I got back out on open roads, the temp gauge went back to below half, and it idled fine. Does that still seem vacuum related? Very strange.

I agree that would tell the story. What a cool app! I did notice when checking for stored codes the obd port seems to have a loose connection as I had to fiddle with it and hold it to get the scanner to work. Coulda been oreillys scanner too. Would a loose port cause there to be no cel/stored info? The good news is I work from home and don't really need the car daily. I appreciate all the replies! Thanks.

Nope no cel. Which seems odd to me. It reaches temp...it was just doing that in very cold weather. I'll report back after the new maf, tb clean, and idle relearn. It may have to go to the local suby guru beyond that. I guess could be front o2, egr, or intake manifold/gasket leak.

NA 2.5 base. I have not checked for vacuum leaks...not sure how to go about that. I was going to try a known good maf, clean the tb, and do the idle relearn when it cools off this wxend.

Greetings. I have an 08 Outback 5mt 164k. Recently started dieing at idle. It's fine when in the cold start cycle but will not stay at idle when fully up to temp. Previous owner complained of this when I bought it. I've driven it 15k and this is the first I've experienced it. Previous owner had a new long block installed. I mostly only drive it in the winter for skiing and ski trips. I noticed this winter when it was cold (below 15f) the car never would get to full temp and would lose temp at idle...like the thermostat is stuck open. I'm now wondering if that's why I never had a problem because it would be in the cold start cycle the whole time? I dunno. It's probably going to be hard to diagnose as it won't stay running unless you hold the revs over 1k. Any ideas? TIA.

Wanted to say thanks for this thread. Fixed an 08 outback today. Symptoms were no license light and no rear wiper. An afternoon of soldering. Salvaged 16 wire from my buddies work recycling bin. Opted to clip everything (6/14 were broken), remove the boot and solder. Ended up cutting the boot due to lack of foresight regarding width after shrink sleeves were installed. Took us 2 hrs with plenty of beers and breaks.
