Well, It got me last week Thur. I was backing into a parking space and the engine took off. I was looking over my shoulder, foot on the brake, and the steering wheel cramped hard left. The engine started racing like I had floored it. I turned around in my seat and the first thing I thought of was 'is my foot half on the accelerator and half on the brake? No, it was all the way on the brake. I had both feet on the brake now but the tires were squawling and smoking. I remember reading a thread on this site a while ago about staying calm and shifting to neuteral. The engine was still racing. I looked at the tach and it showed right at 5000 rpm. I turned the ignition switch off and the engine back fired and stoped. I restarted the truck and finished my parking with no further problems. I came in and called the dealership immediately. They said bring the truck in and they would keep it a couple of days to read all the codes and open the computer box. They also called me and asked if cruise control was on, air conditioning on, or floor mat bunched up in front of the pedal. No to all questions.
