Surge

[IN BC]

Hello all

I read the thread re white smoke regen issues

Heres what happened to me.

Im pulling up a long hill, in TH mode with an unladen equipment trailer on - 2500lbs. Top of the hill is a traffic light. 50 yards from the traffic light the truck spools up on its own, kicks down and is accelerating like I have the pedal to the floor. All the while kicking a cloud of smoke the military would be proud of. It took me a second to react but I end up throwing the truck in neutral and locking it up. Its still revving smoking etc. I shut it down and when the smoke clears I am through the intersection. Glad it was clear.

It is in the shop and Iwill let you know what they find

I get that also but not when I am towing. I will be sitting at a light and all of a sudden it rev's up to where I have to push hard on the break to not have it move forward. It also happens when I am backing into a spot, it will just start hauling a@# and I have to slam the break before I hit something. Never noticed the smoke because I was to worried about hitting things but after I put it in neutral it stops. I have a job 3 and no updated flashes.

This happened to me as well when I was driving one of the company trucks, it was in reverse and the RPMs probably increased by 300 over what is normal. It certainly gave me a startle, but I didn't notice any smoke nor did anyone that was around at the time.

I'm starting to think these trucks have a mind of their own.

I called the shop. Nothing showing up as wrong. They test drove it and it did the same thing on a lesser scale to the Mech.
It stays in the shop for another day.

Can it be the throttle getting stuck?

mine has started doing this over the last while...White smoke at idle, and then a little puff of white when I take off.

The truck will occasionally start surging when I'm at a stop light or if it's just parked and idling.
