Hi i have a couple dodge rams but im having a problem with my 2001 dodge 2500 4x4 with a 5.9 Cummings it will idle fine but when you push down on the peddle it will not rev past 1400 rpms i have put alot of new parts on trying to fix this problem but still no luck im hoping someone can help me..thanks

 

What parts have you replaced? Lift pump good? You want to be in the diesel section, or second gen ram section.

Move to the correct section an create a separate thread.

 

I have replaced the throttle position sensor and the Turbo also checked the wiring..replace the pickup pump and put it in the tank
