stange noise?
truck has made strange noise 3 times just after start i let the oil come up and then pull out of the shed, small incline to the rear, start to pull out the motor sounds like a gas would if it was running out of gas, no codes on lights if i tap the gas pedal it goes away. it is like the motor is just about to die then back on, my dad says sounds like a shutter. this is not an every day thing just 3 times in the last month.
Thanks Matt

Could be your exhaust backpressure valve trying to close. It doesn't die does it? When it does it again, stay off the pedal and see if it closes giving out a jet engine kind of sound. Normal if that is what it is.

i know but it is so random that i cant get a recoding of it to post, it is like a rumping sound, it reminded me of a video it was on here of a truck that had new injectors and need live tuning, but all stoke here.
