91GPSTE Posted December 12, 2006 Report Share Posted December 12, 2006 I remember asking this a couple of years ago but I forgot what the solution was so I will ask again. When I set the cruise control on my car, it may work for a while and then cut out while driving for no reason. This happens intermittently. I remember it has something to do with a sensor or a vacuum line behind the plenum. Can anyone lend a hand? Quote Link to comment Share on other sites More sharing options...

skiiirt Posted December 14, 2006 Report Share Posted December 14, 2006 Thats most likely vacuum leak. Check all the hoses. It should be fairly obvious by the squeel you hear or the "hissing" noise. Isolate it's location and start replacing. I have been on a never ending story chasing bad vacuum lines. Good Luck Quote Link to comment Share on other sites More sharing options...
91GPSTE Posted December 15, 2006 Author Report Share Posted December 15, 2006 I figured it out together with funny tranny shifts. One of the vacuum lines worn out. Quote Link to comment Share on other sites More sharing options...
