Wags87 Posted April 11, 2008 Share #1 Posted April 11, 2008 The 87 idles good till it gets up to operating temp. Then in traffic the idle climbs to 2000, 2500, even up to 3 grand if I'm in traffic long! Any ideas? Link to comment Share on other sites More sharing options...
muffinman Posted April 11, 2008 Share #2 Posted April 11, 2008 start looking for vacum leaks at the bottom of the carbs and all the lines that would be my first move Jeff Link to comment Share on other sites More sharing options...

ctraylor Posted April 11, 2008 Share #4 Posted April 11, 2008 Did you try turning the idle screw? I know this sounds stupid but sometimes the easy things are forgotten. Link to comment Share on other sites More sharing options...
Condor Posted April 11, 2008 Share #5 Posted April 11, 2008 When syncing the carbs you're supposed to set the idle screw when engine is up to operating temp. I'd think about a carb sync. Link to comment Share on other sites More sharing options...
Squeeze Posted April 11, 2008 Share #6 Posted April 11, 2008 As the Muffinman said, search for Vacuum Leak Link to comment Share on other sites More sharing options...
GeorgeS Posted April 11, 2008 Share #7 Posted April 11, 2008 Check the Rubber Caps, on the Manifold vaccume ports. They might be cracked and rotted. Also, the Vaccum Hose, from the Lft Fwd, carb that goes up to the " Barro Sensor " Link to comment Share on other sites More sharing options...
dkaiser Posted April 12, 2008 Share #8 Posted April 12, 2008 I think that sounds like a possible vacuum leak too But here is the real question -- I f the Carb boots are cracked, what is the solution?

However... I think I just read some where on the board where they manafolds have a liner that will keep any crack from going all the way thru. I think...
