Nope, usually pretty easy. In 1999 I had the the throttle linkage break on a 5-ton truck I was driving up I-10. It instantly went to full throttle, accelerating as madly as a heavy truck can, and I simply put it in neutral and signaled for the next exit and pulled over to the shoulder. The engine was screaming, it wouldn't shut off with the key (diesel) and I finally got it off by putting a book over the intake. Then I fixed the linkage with some wire and drove home.
