On my truck I have noticed when I have ran my truck for a long trip when I stop and want to take off, the throttle will vibrate and it makes a humming noise till it shifts. Please help thanks.

How many miles on your truck and have you had any service issues? Are you running any tuning?

All stock, about 22,000 on it. Like I said it will only make this noise when I drive it for a bit warm it up. It almost sounds like the PTO on a truck.

Anyone??

when was your last fuel filter change?

It's probably your cooling fan kicking in. It won't run but for a few seconds until it shuts back off.

I just changed the filter and not the cooling fan, you can feel it in the gas pedal. I drove it about 400 miles stopped to get a bite and when I was taking off in first it was humming loud and my wife was like what was that? But as soon as I get into second it goes away.

I would take to dealer as it is still under warranty.
