My Dodge Ram 3500 is driving me nuts, the son of a gun keep surging. It’s like driving a car with the ignition cutting off constantly. I have changed the vp44 injection pump few years ago without any concern. This problem is getting more and more frequent. At the bottom of a hill fully loaded with the truck starting surging and losing speed constantly it’s not a very nice situation.
Can someone help me to find out or someone who has had experienced the same problem.
Thanks
Vince

 

mine had a similar issue, ended up changing the TPS and cleaned all my grounding points. fixed the problem for me.

I ordered mine from Geno's. Came with great instructions!
