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.

yup! That's the one, lol.. I was trying to find mine a while back, also.

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
