This is the third time this has happened. The first two times was on open road and lasted 3-4 seconds. I was able to keep it under wraps with just a slightly raised heart rate before it let off. The first time I looked to make sure the throttle was not hooking on the floor mat or anything, which the mat was totally clear of the throttle. That time I had my SCT tune in it, so when it stuck wide open it took off like a rocket. The second time I had it tuned to stock and it wasn't as dramatic but still got my attention. Today, it literally scared the crap out of me. I was tuned with a fast tune and I had punched it to get across the street and let off the throttle half way across the street...except the truck kept going like a rocket. The pedal was not stuck to the floor it had popped back out but the truck was still floored. I had every ounce of strength pushing on the brake and all it did was keep it from going to much faster...I was still going a solid 25 mph with the brakes mashed. I was heading full bore into the car directly in front of me. As a last resort I killed the ignition and was able to stop the forward motion less than 6" or so before smashing into the car in front of me. She quickly stopped at the next stop sign jumped out of her car and gave me the one finger salute, but before I could even start to give her the reason she jumped back in and took off.
I was just wondering if anyone has ever heard of this problem. It's not the chip since it happened once 100% stock. I know these are electronic throttles with redundant sensors...but I thought if they got a false reading they defaulted with zero throttle...not WOT. But anyway, one way or the other I need to get this fixed before I plow right over top of someone one of these days. /ubbthreads/images/graemlins/confused.gif
Thanks for any help,
Glad you were able to act fast.I have a 2018 F350 superduty 6.7 powerstocker and just today the throttle stuck and I had to put the truck into neutral and brake. Scary
