Sound like you need to have the catalytic converter checked. when a catalytic converter gets plugged up it will cause the exhaust pipe to get really hot or red. and show the symptoms you are describing. a good muffler shop should be able to test it. good luck

2000 ram 3500 deisel dies at 2000 rpm won't start
could be fuel elated, there are two fuel pumps, the high pressure pump to feed the injector system and the lift pump to get fuel from tank to the high pressure pump. Check fuel filter also and start there. The fuel pumps are expensive. What have you checked so far and eliminated?

2001 Dodge durango will start if cranked long enough but will not idle and once it gets to 2000 RPMs it begins to fluctuate between 2000 and 2500 but will not exceed 2500. Problem came on fairly quickly...
Could be fuel pump on the way out. Could also be dying battery. Have battery load tested, and replace if its the least bit flaky.

a couple gears might be wearing out and that usually is the cause of the fluctuations. Take it to a transmission specialist such as AAMCO and have them take a look at it. that is the best thing to do.

Fluctuating engine temp a/c sends out cold air intermittently
Here's the thing. The ECU will shut down AC if the engine temperature is too hot. If the coolant temperature sensor is malfunctioning (lying to the ECU) telling it that the temperature is hotter than it actually is, the computer will turn the AC OFF.
