Where is the PCV valve on my model? Cant locate. My car will drop from 500 rpms to 250 and feel as though it is going to stall when stopped. I am cleaning out the in take butterfly and want to try and replace the PCV valve as well. I replaced the alternator 3 days ago and since then idling has been rough.

Thanks

I dont consider myself an excellent mechanic but that shure sounds like a vacum leak.I would double check all the vacume line and make shure u didnt bump one with your alternater installation.U wouldnt believe how rough your motor will run with just one hose off or broke
