Question about 2005 Buick LaCrosse
Sometimes when I'm driving the engine stops excelleration, almost as if the car has a governor on the engine. The tackometer goes from 22,000 down to 7,000 rpms. The engine does not shut off but when you push the excellerator nothing happens.
I had the same problem. It sounds like your accelerator position indicator or (API) is going bad.

Try these in order. Change the fuel filter,check the fuel pump pressure at speed,fuel pressure regulator vacuum at the hose or it's operation,plugged exhaust.These are the most likely causes.
