Check your exhaust manifold for a stainless steel tube and follow it. Was located on the right bank on Gen 1 and hard to not see, so if you don't see that on either side, maybe there is none.

Not installed, AFAIK.
Engines with variable exhaust valve timing control don't need EGR, since the same function can be accomplished by altering the timing a bit. However, I thought that the 3.0 only had variable intake valve timing. I know this is true for the 3.9.

Guys, please look at this thread. It's where I learned that they had dropped the EGR valve mid gen II 3.0 production.
V6 EGR valve location???
I've got a gen2 v6 and I'm trying to find the EGR valve... I've been searching for days to no avail. The workshop manuals dont seem to show its location either. Any help is greatly appreciated. Thank you.

Hopefully you bought NTK ... and not Bosch.
Motorcraft. Changing the 2 upstream sensors seems to have fixed the rough idle
But now it's back to giving the good old p0420 code. fun times!
Bank 1 sensor2 is reading between 0.06v- 0.11v with intermittent spikes going up to 0.65 (maybe this sensor is failing?) and bank 2 sensor2 is reading 0.04v - 0.07v with no spikes.
Bank 1 and Bank 2 Catalyst temps are the same currently at 866°F..

Hooley Moses! That's a lot of codes! You sure your battery is happy?

Most of those are related. I would guess just one root cause for the engine codes. He can probably ignore the two AC codes.
