Cruise Control Stuck On; This is a very Big safety issue, I drove this truck 93 miles and stopped and turned the engine off twice and the cruise control would not turn off and kept accelerating right back up to 52 mph, I rode the break thru two 35mph zones.on a very curvy highway 25mph to 40 mph curves When I arrived at a friends house he opened the hood and wiggled some accelerator wires and when I started it up the cruise light came on then went off,and when I backed up and put it in drive it did not accelerate. I am afraid to turn the cruise control back on?? I have owned this truck 9 months,had no problems until today. Carolyn
