The Chevrolet Silverado, and its mechanically identical cousin, the GMC Sierra, is a series of full-size and heavy-duty pickup trucks manufactured by General Motors and introduced in 1999 as the successor to the long-running Chevrolet C/K line. The Silverado name was taken from a trim level previously used on the C/K pickup truck from 1975 through 1998.
Hi pamledford95206,
At what speed is the bucking happening?
by Blake Klein
Today, it did it from a start.

Blake! Could it be a coil / sparkplug
by pamledford95206
I don't think it to be a spark problem, as the car shouldn't buck if it doesn't fire sometimes. I'd suspect the clutch and/or transmission.

Is the bucking a forward and back motion or side to side?
