Re: seem to have fixed the idle hang
Since I try to post on every idle hang thread, just wanted to mention that John Horton the master Viper tech since 1992 that runs West Coast Viper swears that the secret to killing idle hang is to run the Number Four test, the idle air pass test, on the DRB diagnostics tool the dealer has so that the throttle bodies are perfectly synchronized. My understanding is that you hook up some leads to vacuum lines on the throttle bodies and the machine ends up electronically monitoring how much air is passing over each throttle plate at idle so that you can match them via real air flow rather than mechanically comparing the angle of the two plates at idle. I am going to throw in some guaze filters then get this test done and will be reporting the result.
And oh yeah, weight 50 or so miles before you declare your idle hang dead.
