I have a 1994 Dodge Ram2500 4x4 w/5.9L Cummins 5spd manual trans. I'm
having power problems.

Thanks for the reply Max.

The APPS is an accelerator pedal position sensor, and is used on
electronically-controlled trucks ('98.5 and up). Older engines (12-valve
head) will have a similar sensor (a TPS, or throttle position sensor), but
this is only for automatic-equipped trucks, and is just there for torque
converter locking/unlocking. Fueling on the 12V engines is mechanically
controlled from the throttle cable, directly to a valve on the injection
pump.

Tom,
Thanks much for the info. The dealer did the throttle link upgrade and the
truck does not run right. Is there a way to check the valve, link and cable
to rule this out.

Thanks;
Dave

Yep - take it back to the dealer and say, "it don't run right. Fix,
please".
