Just bought my truck in May, 2002 3500 quad cab, it's the first diesel I've owned, so I'm on a definite learning curve here. Truck runs great, starts right up every time, pulls the 27.5 ft 5th wheel no problem. But here lately in the afternoon when I get off work and crank her up to go home, she'll idle out of the parking lot and when I get to the street and hit the throttle...... nothing happens and she just slowly creeps into the roadway. This will last for a couple of minutes and then all the sudden she'll take off and run great all the way home. I read some earlier posts on how to read the codes and so I read them this evening, here is what I got: P0500, P0460, P1693, Pdone, P0216, P1693, Pdone. Any help would be greatly appreciated. Thanks,JBK
