Truck doesn’t change gears smoothly

[Rawze]

If you have leaky injectors or if the metering actuators are leaking and worn out, it can be harder then normal to shift, as the engine does not rev down as well as it should when letting off the fuel pedal.


Run an overhead valve adjustment again and then do an injector leak test on it.

A person can also monitor the live fuel flow into the engine to see if it goes to zero mg/stroke while idling.. or fluctuates around up and down like a sign wave. This is an indication that there are issues with a metering actuator.
