I have a chevy silver ado , and yesterday it wouldn't allow me to get of 55. And now today it started not allowing me to accelerate. And it is now completely broken down. Help please.
The symtoms you describe could be caused by any number of things, some simple and some more extensive -- none of which anyone here on this answer board can diagnose or repair for you. Get your vehicle to a repair shop soon, before it damages things even more.
