Dealer or a junk yard and thats it that I know of.
But you need to do a fuel pressure test. Rent it from Auto Zone or something.
Whats the TPS voltage and is it steady through out throttle position and it should increase without variance? You can test without starting the motor. First wire should have no more than 5 volts and it meters through the middle wire and as you increase throttle plate (like your opening the throttle) you see the voltage increase and should never go over the 5 volts. Most stop at 4.5 volts and it should stop there.
Also seen transmissions output sensor trigger that code.
Did you clean your Throttle Body and IAC sensor?

I did clean the TPS and IAC with WB40 and I have a fuel pressure gauge I just have to find it. When I clean the TPS and IAC I also pulled a few spark plugs (coppers) none of them seemed fouled and I also switch around some of the coil packs and it started up better but within a few miles the truck starting bogging and misfireing again. Threw the same p0304 code i've been getting for awhile. I also looked at the harness it was sunlight and hard to see any damaged wires. If I were to examine the wire at night would it be possible to see the bad connection better? Also please remember how this problem started. My mom thought it would be a good Idea to clean the engine while I was out of town and sprayed the engine and engine bay with a hose.

This local dodge recycler had one for $350, but he seemed a little shady. I also found one for $150 but it's for a 02' Dodge Ram 4.7 and I have a 01' Dodge Durango 4.7. I'm pretty sure it will work. What do you think?

This PCM is new and comes pre-flashed to your trucks VIN# (Which you have to do at the dealer!) and it's only $199 shipped.
