Have a 2002 Dakota with the 4.7. It is surging when driving, jumping 300-2000 RPMs. Seems to do it more after the truck has drove and warmed up. Also seems more noticeable after refueling. Had a faulty fuel pump a few months ago and it was replaced and everything was good. Almost acts the same, but had the fuel pump tested and it was good. Any ideas?
