I have a 00 gp gt wit 139 k and I know this car for running fast. Now my question is why is it running like the engine is heavy aka slow. I thought it needed a change of oil which I did and the same. Can any one help, what could it be? Could it be the engine? Because I hear this light noise on the engine like a whooping belt sound lol for real though but really really light especially right now since chicago its cold and one I turn that engine on I could hear that sound.
Also I want to know what happens if the oxygen sensor from bank 2 is messed up, what could happen if it gets worser?
Hope N e 1 helps thanks
