Hello I own a 2006 Grand Prix 3.8l not supercharged. I have the code po440 in and I am assuming it is my purge solenoid valve. I have a haynes repair manual and it states that the solenoid is beside my coil pack on the 3.8l, but it is not. Although through internet searches I have seen engine schematics of a 1997 3.8l with the solenoid beside the coil pack. Anyone have any clue as to where I may locate it?
