Guest rXSNRG Posted August 1, 2003 Share Posted August 1, 2003 It's idleing fast (1500) and does not want to start when warm. It's not displaying the check engine light. I couldn't find a obvious vacuum leak. '87.5 RX Coupe Anybody have any ideas? Quote Link to comment Share on other sites More sharing options...
Guest GlCraigGT Posted August 1, 2003 Share Posted August 1, 2003 Your auxiliary air valve may be stuck open Quote Link to comment Share on other sites More sharing options...
Guest rXSNRG Posted August 1, 2003 Share Posted August 1, 2003 Is there a easy way to diagnose that? Quote Link to comment Share on other sites More sharing options...

Guest Skip Posted August 1, 2003 Share Posted August 1, 2003 The AAV Craig speaks of, is on the goose neck (thermostat housing) it feeds air into the intake plenum (Al part over the throttle body that says "Subaru 4 wd") The nipple for this is on the underside and is about 0.5" in dia. You could check to make sure it is connected and then pinch the line to it off with needle nose vise grips or similar Quote Link to comment Share on other sites More sharing options...

Guest baccaruda Posted August 1, 2003 Share Posted August 1, 2003 hey mark. you should take the AAV off of the neck and check to see that it's clean, too. i once had a piece of crap in an AAV that played hell with my idle. good luck.

Guest rXSNRG Posted August 1, 2003 Share Posted August 1, 2003 I check the hose, everything Ok. The contacts were dirty, I cleaned them and it didn't help. I pull it and take a look underneath. Quote Link to comment Share on other sites More sharing options...
Guest wjmgl10 Posted August 1, 2003 Share Posted August 1, 2003 Take the AAV apart, and clean it with carb cleaner from NAPA, and reseal the gasket with a light coating of silicone. That helped me out...but it was on my 86 GL-10...but its worth a try.... Quote Link to comment Share on other sites More sharing options...
Guest GlCraigGT Posted August 1, 2003 Share Posted August 1, 2003 i just remembered something, there is also a fast idle solenoid that should kick on with the AC maybe it's not turning off. Quote Link to comment Share on other sites More sharing options...
