Okay so I have a 2003 Dodge Ram with a 4.7 Magnum 105,000 miles. When I am driving the RPMS will fluctuate about 400 to 500 and when I come to a stop it acts like it wants to stall and some times dies. I also noticed that it is running a little warmer than usual but contributed that to the fluctuating RPM's overworking the engine a bit. I took it to the dealership and they said that my air filter need to be changed, he throttle body and injectors were dirty and the Bosch Platnium +2 plugs needed to go. I let them do everything but the plugs and it work fine or a week. Then it started acting up again so I took out the plugs. That helped for about a day. I have check the Idle Air Control Valve and the throttle body positioning sensor, both appear to be fine. Somebody please tell me what is wrong with my truck?

 

The 4.7 guys will chime in, any check engine lights or codes coming up, like Map sensor or plugged PCV, good luck and welcome to DF.

 

No check engine light at all. Gonna change the PCV Valve tomorrow. Hope that works. Also read something about a camshaft position sensor wonder if that could be the problem.

 

I am having the same problem with my 2003 Durango 4.7, did you ever figure it out?

 

Change the TPS and it will be back to normal.
