What was your scariest cobra moment?

[lamaluv]

I had my fuel injection on the car for about six months and was accelerating up to hiway speed of 65mph. The speed limit dropped to 40 and when I let off of the gas the rpms stayed at 5500. The throttle was stuck and I was still gaining speed. I quickly hit the shutoff switch and pulled onto the shoulder. I found a bolt from the linkage had come loose and jammed the throttle wide open.
