Hello from Aberdeen, Mississippi, today I was driving on 4 lane highway at 70mph, I came up on slow moving vehicle so I broke the cruise control by pressing the cancel button as I started to pass. The Service Electronic Throttle Control lamp came on just as the truck started to accelerate on its own. The accelerator went to the floor, I stood on the brakes and was able to hold it to 80 mph, well traffic fell in behind me I guess they thought I was going that fast intentionally. Then all of a sudden it went into limp mode almost got rear ended , it slowed to 35 and then started back normal. This is the second time this has happened, the first time they said it was caused by having left foot on the brake and accelerator at the same time. From that point I have been very aware not to do that. Still waiting on diagnosis. I was jus wanting to know if anyone else was having this problem.
