   For a few months, my '88 Toyota Pickup with a 22R engine and 4-speed   
   trans, has had a slight hesitation above about 50 MPH in high gear. The   
   same hesitation is there at lower speeds in lower gears, which leads me   
   to believe it's an ignition problem. If I'm going up a slight hill,   
   there's no hesitation, so it sounds like it's related to vacuum. Is it   
   possible there's a broken wire in the distributor that momentarily   
   looses connection at a certain vacuum level?   
      
   This hasn't been a real problem since I drive less than 100 miles per   
   week and seldom drive at freeway speeds.   
      
   I'm thinking of replacing the distributor, to the tune of around $160.00   
   for parts.   
      
   I have a mandatory smog test coming up at the end of October, so am   
   thinking I'll see how it goes. If it fails, I'll replace the distributor   
   and have it retested.   
      
   I had thought, at first, that it may be fuel related, but have pretty   
   much ruled that out since it's fine at wider throttle openings. It has a   
   fairly new fuel pump and the filter has been replaced. It ran fine after   
   those changes, and started the hesitation a few months later.   
      
   Any help would be appreciated...
