You're right, because it absolutely can. My first car was an older Oldsmobile Cutlass with the 307 engine. The cruise control module (vacuum operated) was mounted to the intake manifold with a hard rod that connected the diaphram to the throttle lever. That rod would sometimes drag on the floor of the intake manifold and stick. And that was truly a STUCK throttle; you'd have to stop the engine and open the hood and physically UNstick it. Oldsmobile recalled the cars and installed a washer doohickey that would keep the rod from dragging on the floor of the manifold.

Unintended acceleration events are nothing new in the automotive world. In fact, it's possible that they are less likely today without the sometimes Rube Goldberg-like throttle/cruise control cable setups that I've seen in the past.

Wow...would I enjoy jumping into that one for a vigorous debate. But that would get into politics and nashing of teeth, pouring ashes upon heads, etc. and close the thread.

I will add that politicians are idiots and leave it at that.

This is so true. My 68 Impala drag car (427 with about 600 rwhp) stuck once, and all you did was turn the key. But I have seen cars wrecked and otherwise destroyed due to folks getting panicked and not acting smart under pressure.

I also had another 68 Impala that actually had a factory recall on it to install a cable around an upper suspension piece to prevent stuck throttle if a motor mount broke!

Both very appropriate responses, gentlemen!
 
I think the OP really should have lied/modified his story a little bit and just said that he had his right foot on the brake. Would have saved 8 pages of off-topic arguing.

HAHAHA!!!! Perfect!

The truck is possessed, as it continues to do this at odd intervals. Thank goodness it does not go "full throttle" by itself. I've taken to putting it in park when ever I am at a stop light or similar.

Goes to the dealer as soon as I fix my Jaguar...

I'm beginning to think you are right
