michaelbteam Posted November 10, 2006 Share Posted November 10, 2006 90 legacy wagon, starts fine but won't idle until warmed up. Must be a sensor--I know I'll figure this out but wonder if someone knows the answer to save me some trouble. Thanks if you do! Quote Link to comment Share on other sites More sharing options...
Manarius Posted November 10, 2006 Share Posted November 10, 2006 I'm going to go with IAC Valve on this one. Idle Air Control Valve to be specific. I don't have a picture of it, but it usually needs cleaned after a while and this is one of the symptoms of it being dirty. Also check to make sure you don't have any flailing vacuum lines.

tcspeer Posted November 12, 2006 Share Posted November 12, 2006 I also like the two answers above, mine done this a while back and I sprayed carb. cleaner in the hose that goes to the idle air valve and it seems to be what finally got it running right. If you will do a search for idle air control valve you should be able to find the proper way to clean it right. Quote Link to comment Share on other sites More sharing options...
michaelbteam Posted November 12, 2006 Author Share Posted November 12, 2006 Thanks, folks, I'm on it! This is another bargain runner, relatively clean 90 legacy wagon with about 200K miles. A 2 owner, the guy just put axles, brakes, and a clutch in it and had to sell it--$900. Needs front end 'something', need to figure that out and have a good backup to our two 93 wagons.
