CHEVY PCV VALVE

2003 Chevrolet Tahoe

Engine problem
2003 Chevy Tahoe V8 Four Wheel Drive Automatic 124, 00 miles

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
