    Air is getting in, check your vacuum lines...in particular the elbows as they are the first thing to go. First one I would check is the one that is just inboard of the power steering pump...under the upper radiator hose. That one always goes first. If that is is, do yourself a big favor and replace them all now, as this is the beginning of the end of them.

      Excellent! Thanks for the reply.. I'll check them.
      I did hit the injectors with a quick squirt of carb cleaner .. at the end
      of the rail.. or should I say the input to the rail I did notice a change
      in idle speed....
      Ill go through the vac lines also..
