hello guys im new to the site and was hoping to get some help with my 2008 lr2.i was driving home from work the other day and i noticed my check engine light came on, i scan for codes and got p0171 and i also noticed the car was making a whining noise i thought it was the alternator making the noise but after fooling around with it for about an hour i tooked the oil cap off while the engine was running and the noise was gone.then i put my hand over the hole and it sucked my hand in like a big vacum leak. i checked for collapsed hoses didnt find any. does anyone know if the pcv system has anything to do with this or what to look for?
thanks in advance
