   Jim and Al,   
      
   Thank you for the prompt response. I've read other threads about the   
   EGR, but hadn't thought about it in this case. I think it's a problem of   
   not seeing the forest for the trees.   
      
   I'll dig in to it and report back.   
      
   Again, thank you...
