Thread: PCV valve Location and Vaccuum diagram?

So Im throwing a P0171 code in my grand prix gt and ive yet to figure out why the bank is lean. So far i havent been able to find a vaccuum leak but Ive never replace the pcv valve in it either. I cant tell a loss of power but sometimes the car will pulse and when i come to a stop the car will come to a low idle. If someone could show me a picture of where the PCV valve is located I would greatly appreciate it and a Vacuum line diagram aswell. Thanks!

98 right?

Thank you guys soo much! Got my PCV valve replaced today and changed the oil. Now is it possible for my cold air intake to be leaking air and throw that system bank too lean code? It seems now that ive replaced the PCV valve its not pulsing at idle anymore. Thanks again!
