Locating EGR on 2000 LS6

I am trying to locate the EGR on a 2000 LS6 as I work thur the cheapest and easiest solutions to P0171 and P0174 codes and stalling at idle. If anyone has any pics that would be appreciated.

I think I would look into a vacuum leak as the problem rather than the EGR.

There is another thread on these codes, 4 pages of posts. The PCV elbow is a known issue with the V6, and it essentially is a vacuum leak.

The EGR on the V6 is a very straight-forward item to swap on the first gen. Open the hood and it's right there next to the throttle body. Pull the vacuum line, remove the exhaust hardline, then pull the two 10mm bolts. Be careful not to lose the gasket.

Thanks for the info, I suspect I will be removing the intake manifolds and replacing the PCV elbow...but I'd rather do the cheap and easy stuff first to eliminate all possibilities
