12 Valve 2.8 V6 EGR diagram?

[Eric Langheinrich]

Anyone happen to have a diagram of the 2.8 EGR system? 

Last time in the shop for my check engine light my mechanic told me the EGR was reporting "slow". The problem at that point was a stuck thermostat, so he didn't bother to do anything about the EGR. The light was off for about a week before rearing it's ugly head again. Since I'd rather avoid a third $300 trip to see Tony, I figured I'd at least try this one myself. 

I read on the bently page that there is a passage on the drivers side rear of the engine through the intake manifold, and that the passage can get clogged causing EGR codes. I figure that's the place to start, but would really like to have some sort of diagram before I do.

Thank you,
