Problem got to the point the truck would barely pull itself down the road. I had enough trying to fix it myself and took it to a very reputable mechanic. After two weeksand lots of head scratching and parts swapping he finally discovered that the timing was off by three teeth. Runs like a champ now and doubled my fuel mileage.
