    Got my old truck running but it has a rough idle, your ok going down the road but when your sitting still in drive it want's to cut off. My son did a little test on he sprayed some brake cleaner on the intake and in one spot the trucks RPM's went up. Is that a sign of a leaking intake gasket. Thank's for Ya'lls help.:confused:
  2. yes, an intake vacuum leak will cause a rough idle.
