doobaruGT Posted July 13, 2009 Share Posted July 13, 2009 So yesterday I get a break in traffic on the freeway and zip around some slow folks. I drop it in 4th and take off. When I hit 80 or so, the car felt like it was suddenly restricted, almost like I lost a cylinder. It's a 2005 LGT with about 85K on it. When i reached the exit a mile later, I shifted to neutral coming down the ramp and the car shut off. I came to the end of the ramp and restarted, very nervously. It turned over no problem with everything in working order and no CEL. Now the idle is shakey (at about 500 rpm's and it struggles to stay running. Plugs, wires, pump...? Help! Thanks everyone!

Spec B Posted July 13, 2009 Share Posted July 13, 2009 Sounds like you blew a vacuum hose under the IC. Link to comment Share on other sites More sharing options...
doobaruGT Posted July 13, 2009 Author Share Posted July 13, 2009 I would agree with that except I know what that's like. I haven't lost quite that much power and I still have boost which means I'm keeping compression. Thanks for the suggestion :-) Updated parts list since original part-out here.

Spec B Posted July 13, 2009 Share Posted July 13, 2009 I woudl check the IC/throttle body connection next. Since it happened under boost, I am guessing something just popped off. Link to comment Share on other sites More sharing options...
doobaruGT Posted July 13, 2009 Author Share Posted July 13, 2009 Gotcha! Thanks for the help. I'll let you know what I find. It makes a lot of sense! Updated parts list since original part-out here. Original Full part-out of my LGT HERE! Link to comment Share on other sites More sharing options...
doobaruGT Posted July 14, 2009 Author Share Posted July 14, 2009 It was the IC. When I installed my downpipe, I don't think I put the seal on correctly. Which is why when I gave it more throttle, the gromet popped off. The was also a vacuum hose off beneath the IC. Thanks so much for your help! Updated parts list since original part-out here.

BennyNW Posted July 16, 2009 Share Posted July 16, 2009 I just bought a 2005 Outback XT and there is a heavy idle after the car has been drive for about 5-10 minutes. I took the car back to the dealership cause there was a differential leak. They replaced the axle seal (on Subaru) and did some other minor tweaks. The mechanic told me that the Subaru turbos can have a hard idle. Is this really the case? 2 of my buddies have WRXs and they don't idle like this. Any thoughts on what might be wrong or what to look for? Link to comment Share on other sites More sharing options...
doobaruGT Posted July 17, 2009 Author Share Posted July 17, 2009 By "heavy idle" do you mean lower and shakey? Updated parts list since original part-out here. Original Full part-out of my LGT HERE! Link to comment Share on other sites More sharing options...
BennyNW Posted July 20, 2009 Share Posted July 20, 2009 It idles at around 600-700 RPM when at rest in neutral after being driven for a bit and it is a bit shaky. Just heavier idling than I had with my previous Outback (although that wasn't a turbo). Let me know what your thoughts are. Thanks Link to comment Share on other sites More sharing options...
