engine surging problem
i've been having a few issues lately with my engine surging under certain conditions. every time i go up a hill when i'm in overdrive, the engine will start to surge. everytime i gas it, when im in overdrive, going up a hill, it surges ALOT. and sometimes it will surge when i'm coasting downhill.
just curious if anyone has any ideas as to what this could be. any info is appreciated. thanks!

the tps is normally what causes surging under load.
surging with your foot off the gas can normally be blamed on the IAC.
the brake switch can be to blame.
the wires on the bottom of the valve body on the transmission could have rubbed through the insulation.
what fixed my surging after a new tps, iac and camshaft position sensor was doing the spark plug wire re-route.

there is a bundle of wires on the bottom of the valve body that you can see when you drop the pan. one guy had them rub through and posted about them making his truck surge for a while.
the re-route and new spark plug wires finally got rid of it for me.
i forgot to mention new wires earlier, the #7 wire had a crack in it right next to the boot.

Here is the post about the tranny harness, https://dodgeforum.com/forum/2nd-gen...ise-speed.html
And here is the TSB for the spark plug wire reroute, http://dodgeram.info/tsb/1998/18-48-98/18-48-98-v8.htm
Of course I still suspect the TPS 1st and/or IAC.
