Gimpy117 Posted April 11, 2009 Share Posted April 11, 2009 1990 subaru legacy 2.2L AWD auto when I start the car cold it often idles very bad were talking the RPM going back and forth from 800-250 rpm (maybe even below it reaches the line and the very bottom of the rpm gauge but never stalls) Is this an Idle sensor? any ideas?

KnifeyMcShanker Posted April 12, 2009 Share Posted April 12, 2009 Well, just visually inspect them all for cracking or hardness. I recently went through and just replaced every single one of mine. I got 8 feet and it was about the perfect amount, only took like 45 minutes too. Link to comment Share on other sites More sharing options...

KnifeyMcShanker Posted April 12, 2009 Share Posted April 12, 2009 Just pull a short one off in the parts store parking lot and ask them to match it. That's what I did. Link to comment Share on other sites More sharing options...
Platinum_Racing Posted April 15, 2009 Share Posted April 15, 2009 My 92 does that also. Spark plugs and re-routing the vacuum lines helped, but every once in a while she still does it. Might just be tired... still runs fine though. Link to comment Share on other sites More sharing options...
