Ok so heres whats wrong. i start my car in the morning to go to school. When i start the car it wants to bog down when i rev it up. After it sits at idle for 5 mins it will then rev somewhat close to the way its suppose to. After letting the car sit for about 8 hrs it wants to bog down again when i start it and rev up a little bit. what could be the problem? Its a mustang gt automatic. x pipe with 75 shot nitrous. has cold air intake. clean air filter. new oil chang and tranny fluid changed.

I was thinking maybe spark plugs? but i havent checked any of it yet. Im just gonna change spark plugs, wires. but i have nitrous too so my fuel injectors could be bad? I dont wanna spend money on spark plugs and it be the fuel injectors but i guess im gonna have to give it a shot.
