My neighbor has a 96 cummins and when reved or jus throttled quickly it revs fine but when you let out it dies???

 

the idel set?

 

Is the truck warm when that happens

 

Ya it'll do it anytime. Idk if the idle is set rite.

 

whats it idel @? if its an auto it should idel @ 850rpm with ac on and the truck in gear if its lower than bump it up manual truck just set it @900 or so with ac on....or off if you dont have ac......hope that helps, helped me when my truck was stalling...

 

alright well how do you change the idle???

 

theres a set screw that determines where the throttle lever stops... its torwards the back of the block. move the throttle lever on the side of the pump and you should see the lever moving back there two. 10mm wrenches ones for the head ones for the jam nut. you have to hold the throttle to the floor while adjusting it (engine not running) when you start it up to check your adjustment... if you havent tightened the jam nut expect atleast an extra 100-150 rpms gain after it's tightened. just a heads up; it can be a real pain to get it set right where you want it... it can be real touchy

 

i need to set my idle in park its on 500

how would the valves or push rods get bent?

 

It dies after revving????...
Sounds like the motor is sucking air into the fuel system somewhere.

 

Ya if ya jus rev it fast. I haven't had time to go check it yet since it isnt my truck i might here in a few.
