99 Dodge Ram 4x4 owner here also, Most Auto parts stores will do a free plug and play diagnosis if You can drive Your truck to them, That will give You the problem codes and if the salesman knows His stuff He can tell You the coded problem meaning and what part/service is needed to remedy if any, might just need a reset, I eventually purchased a DB II tester for myself as I have multiple vehicles and cant always get to an auto parts store, Good Luck
Had the same problem. In my case, the wiring harness was scraping against the vibrating motor and wore through the insulation. This caused the computer to think the throttle position sensor was bad and the RPMs were erratic. The engine light came on and indicated TPS. A short time later, more of the wires became damaged and the engine started missing cylinders. My problem was at the top rear of the engine where the harness runs over a metal stud (right behind the valve cover). Check your wiring harness. Not an easy find until you actually look for it specifically.
The rpm variation you are noticing is the torque converter slipping in and out of lockup. Most likely the torque converter clutch is failing, you will most likely need a new converter, if it's got a bunch of miles on it I'd probably freshen up the clutches while I had it out.
Believe it or not....this is actually normal depending on which oil that you use. Some of the thinner oils will cause this to jump around and the thicker oils will make it jump around less. When you first start the truck the oil is thicker and will read a high psi then get lower with less rpm while the oil warms and then gets thinner then builds pressure again with more volume being put through the engine while you drive down the road hence going back up to 80 psi. This is typical winter issue with the Dakota's in general. I would only be concerned if the pressure bottoms out while driving or starting.
