Stalling an engine

stalling

#1

I have a 1997 dodge w/cummins diesel-the problem is every time I have the air condition on the truck stalls, as soon as I let off the pedal. It has been very dangerous as it has stalled in the middle of turning and going down hills etc.,


#2

The throttle position sensor should be checked.


#3

Dirty throttle body or sticking idle air controller.


#4

Dirty throttle body or sticking idle air controller.

On a diesel?


#5

Most vehicles (gasoline or diesel) have a power increase function in the computer which will add more fuel when the A/C is turned on. Yours may not be working.


#6

FWIW, diesels don’t have inake throttles or Idle Air Control valves. Fuel flow controls RPM/power.


#7

I’m wondering if the AC compressor is binding and loading down the crank too much to idle.
