I just bought a 2001 2500 4x4 6 speed 100k miles first thing I did was put on a

Raptor drfp 19 idle 16 wot I was driving down the highway at 70 and it started to surged and had really bad dead pedal so I got home and ran the codes and got po216 not sure where to go with that

IIRC I got mine from cummins for a good bit less but do remember how much. Did not have to use it, YET!

Check genos garage

Geno's has them for $32.
