I appreciate all of the suggestions. The codes that were showing were the low voltage and the dreaded in jection pump. I did find that the ground cable was most of the problem. The surging has stopped and all other problems except that when I start the truck it runs up to about 10 miles and hour and you cannot accelerate from there. It seems the only cure is to cut the engine off and restart. It usually works fine from there. There are no codes shown.geraldg

02 dodge 4x4 - Truck seems to unlock converter from around 50 to 60 mph. RPMs go up and down about 200 rpms. At times the throttle can make no difference if it is on the floor or not, the engine stays at the same rpm. We replaced the apps about 6 months ago and it seemed to cure the problem, but it is back.
