Starts with throttle open revs up and will idle up and down breifly and dies out and if it does actually idle as soon as you try to open the throttle it sputters and shuts off. i have done timing set new crank and cam sensor air temp sensor on intake ambient air sensor canister purge valve and need idle air control and replaced the tps and still wont run right

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

That is the proper idle speed if the A/C is on.
Did you clean the MAF good ?
Vacum hose leak secondary air leak ?

Sticky throttle body buterfly , clean it with carb cleaner.

First off, how new is your battery and how many miles on the D? Dodge vehicles are very sensitive to a failing battery. Have it load tested, and if is the least bit flaky, replace it.
After that, the TPS or throttle postion sensor is your next.
As far as the revving up and down above 3000 rpm goes, that is the PCM protecting the engine from over revving.
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
