Default EGR Valve Location?

I've searched around but can't find the location of the EGR valve on my '02. I really would like to clean it & see if I can get my mileage back up.

It's not infront of the throttle body like I've seen in other pics, hopefully it's not behind it, what a PITA that will be lol

The 2002-up 4.3 uses a different system, I beleive. No EGR up in front of the intake manifold.
Also, using the search function would have negated the need to post a thread. This topic has been discussed many times before.

A different system?... ok because I was thinking I was blind lol, thnx
& I have searched, searched for EGR, EGR Valve... EGR gets a 0 lol, but I found another thread (finally) with a remark from Kyle that says later model 2002's don't have an EGR valve.

so with no EGR valve that could leave an O2 sensor thats buggered up that could be causing the crappy mileage im getting IE: maybe 12 mpg

today I cleaned the MAF, air temp sensor, air filter, replaced the PCV, new plugs, rotor, dist. & wires were done a year ago, updated & reprogrammed the Hypertech
had three DTC's 101, 172, 175 ... air flow & running rich in both banks hmmmmm
