Hi everyone this my first post ot this forum. My GP is my first experience with this model.Well after 154K+ and still running VERY strong.With only a fuel pump replacement.The car has cost next to nothing.It is arguably the best car I have ever owned.On my 2000 GP SE 3.1. I can't change the vent position.Is this a caused by a bad vaccume line?Or a actuator.Or???.Dose anyone know where this system located? Thanks for any responce.
