The 02 model seems to have an unusual number of posts with "surging/pulsating" engine problems related to the injection pump and the 0216 code. Mine has started doing this to the point that I will not take it on any trips-I take my old trusty 92 Cummins. As much as I like this truck I am considering selling as I have had to replace two trans. sensors,speed sensor, lift pump and now it looks like the injector pump is next. This is not normal for a vehicle with 58,000 miles.
