Recently the power from my 2002 Diesel has become inconsistent. If the truck sits for a day or two, it take a mile or two before it feels normal as far as power. While driving this first mile or two, the engine just seems to lug. This is with no load in bed or trailer. This has a manual trans, so you can normally feel the torque through the gears as you shift. I use this truck mostly for commuting. Today while coming of the Interstate after about a 20 trip, the same symptoms again. These cleared up and I was able to drive home. Call the dealer, asked for a possible explanation of cause. He was at a loss. The truck has 65,000 miles, could this be a fuel filter problem?
Any ideas would be appreciated.
