I have a 2000 Nissan Frontier King Cab SE, it's a standard transmission...
Today I'm driving along and I suddenly notice that I have to press down the gas pedal farther than usual to get the same ammount of "rev" out of it. This happened again about 1/2 a mile down the road (I had to press it down even farther than the first time). Eventually the gas pedal went completely flat. I can floor it and the engine doesn't respond. my car starts just fine, but wont respond to the pedal. What could this mean?
