6.2L Stalling Off-Camber? Nose Down?

[Lizard Dog]

Hi guys thanks for following up. The truck went under the knife at the end of last year and I still haven't gotten it back on the (off)road for a proper shakedown.

(Installed a lift and 3/4 tons, H1 wheels/tires)



I'll report back if I'm still stalling with a new filter. I replaced the lift pump about 10k miles ago.

Ok well pulled my filter off gave it the "blow" test. Not sure how effective it is but seemed clean easy to blow through.

How is the truck's idle speed? I would imagine if it was on the low side, doing some technical hill descent would tax the engine by being hard on the brakes and steering. When my truck idled too low, it would almost stall just trying to park because I had my foot on the brake and was requesting full steering assist.

Great, have a beer to get the diesel taste out of your mouth and replace the filter. [:

Ok so filter didn't help the problem. Could it be bad diesel? I don't know how old the fuel is or if it has any stayfuel

As mentioned before, it could be air leak or bad lift pump. Testing the lift pump is easy. There is usually a hose coming off the top (passenger) side of the filter base. If not, add a hose to that nipple, put the hose in a clear container, open the black plastic valve, crank the motor, the container should fill with diesel pretty quickly. If air bubbles do not stop, you have a leak in line before the filter base.
