When I set the cruise control there are now two problems;<br>1) When the temperature is cold outside when I hit the coast button the truck simply accelerates until it reaches 80-85 MPH and then sets itself. This only happens the first couple times that I try to set the cruise then it seems to work fine.<br><br>2) While the cruise is set there is a sputtering that can be heard from under the hood. If I press the accelerator pedal very slightly, not accelerating but just tapping it, then this noise goes away.<br><br>Does anyone have any ideas?? Could these both be caused by an air leak in the cruise control system??<br><br>Any thoughts or ideas are greatly appreciated!<br><br>Thanks,<br><br>Mike<br>

 

This sounds like the old problem that should have been fixed in a recall some time back where the vacuum pump pushes oil down the cruise control vacuum line.<br><br>Pull the vacuum line and look for oil in the line. A Q-tip run down the hole and then inspected will tell you if you have oil.<br><br>If you do, call your Dealer and provide them with your VIN and have them check to see the vacuum pump fix was made.

 

Thanks for the reply RCW. I will check this out!

 

I have been haunted by this problem since I bought the truck in 1997, 2500 standard. The dealer has replaced the servo twice each time it would work for a while until the lines got foll of oil. The truck finally went out ouf warrenty. They know of no recall? Thanks for the info I guess I can fix it myself. Was there a recall??<br><br>Thanks John
