Cap and rotor were in real bad shape...and lucky me, the bolts snapped off while I was at it. Sheesh
New cap and rotor made no changes in the miss.
Plugs look good, wires look good. All seem to be firing when checked...

I just put a code reader on it....discovered that the check engine light is inop
Shows hi-voltage on the TPS
missfire on cyl 5
missfire on 2
random missfiing
I decided to check the compression on a few cylinders. I was most concerned with what 2 and 5 were at but checked a few others to compare to. Although they werent fantastic (120) they seemed consistant.
The plugs appear to be firing with the exception of #2. ..Its very wet
Not wanting to rush right right out and just buy buy buy, I swapped the plugs and wires around to see if 2 would dry up...never did.
I believe the TPS is my late and firm shift problem...
Bad injecter maybe? How to test?

Are you getting fire to plug number 2? If you are, replace that plug. If it is a champion, once fouled, it won't clean up. Not by itself anyway. (in my experience)
To test your injectors, first, ohm test them, don't recall what the standard resistance should be, 16 ohms?? if they all check out good, lift the fuel rail from the manifold, Unplug the electrical connector from the ignition coil, turn the key to pressurize the fuel system, and see what happens. if you don't have any leaks, crank the engine a BIT, see what spray patterns look like, and make sure the injector doesn't stick open.

Ill check the ohms and spray pattern

And after you try that, and you get released from the burn unit at your local hospital, swap that injector with another one on that rail and see if the missfire moves to the other cylinder. Do this too, http://dodgeram.info/tsb/1998/18-48-98/18-48-98-v8.htm. And get a fuel pressure tester, check the pressure and see if it holds. If not, turn the key (without starting) and clamp the supply line to the rail. If it holds pressure the injectors are fine.
