my 03 is bucking

[Brian D]

My 03 seems to have a problem while the cruise control is engaged and going down any slight decline in the road. The truck starts bucking back and forth. To the point that I have to shut it off and then turn it back on when I get back on flat road. I searched under cruise control but found nothing.

Does any one have an idea what causes this and how to fix it.? I recently swaped out the cruise controls on the steering wheel and the problem went away but for only a short time.(Not releated== the on / off broke)



thanks

Brian,



This has been an issue with the ST..... Funny that it comes and goes on the ST..... MY 03 and 04 both did it, the 03 stopped doing it and i sold the 04 ....



Its annoying but seems to be a "normal" thing....



I know i did not like it...

Feedback from the Speed sensor to the Throttle actuator, and there is nothing you can do about it except put your foot on the accelerator pedal just slightly untill you level off.
