So I changed the fuel pump. Not only was there only a slight change in the psi reading since it reads at exactly 30 now, but the prime was the same (3psi) and the check engine light still comes on.
Plus I figured out the the "rumbling" that I was feeling could have been the differential slipping due to low fluid. I changed the differential fluid and only about a third of the recommended oil must've come out. I'm waiting for the rtv to cure, which won't be finished until after I've gone to work today so I'm filling her back up with the proper fluids and 2oz of oil stop leak to see if that does the trick tomorrow. If it doesn't I'll have to replace the pinion seal where it's leaking at a later date.

Oh, and Oreilly auto now carries an odb scanner that also can read odb one -I was the first person to get to use it, too :)- and I was able to clear the EGR code officially by performing a test. Problem though was that the check engine light wouldn't come on for me before I made it there that day and I haven't had a chance to get back there and use it again after getting there with the light still on so that I can read it. The code doens't seem to be storing itself into memory.

Because if you have a limited slip differential it has side clutches that allow one wheel to turn faster than the other during turns. They are inactive when driving straight ahead.

Huh? "Stop leak" > FOR THE DIFFERENTIAL? NO. If it's leaking it's at a seal to replace then WHY it wrecked a seal. If it's "Limited Slip" there is an additive or change it for proper gear oil for those isn't the same. Never for me but heard of the "chatter" on a corner maybe they are complicated with friction clutches that have to release - a wet clutch something NEVER had to deal with one.
If a bearing shows any "play" at driveshaft or at wheels other than some in and out that's a reason to cause a leak OR use of lots of wrong cleaner on those still a never for me millions of miles worth on these.
IDK I might be hesitant to fix one rather find good used if whole unit swap over all other parts almost no guarantee last one was bent by a rock backing into it hard!
EGR and OBD I? Codes at best are marginal for accuracy still could be but asked if you sprayed it with like carb cleaner if it leaked would alter idle better or worse and shouldn't. May have already said this thread got long is difficult to re-read whole thing and all suggested just what was ruled out yet?

The EGR work is done and the code's been gone for weeks now, so I'm hunting for a new problem; that's why I was gonna call this thread closed earlier.
I'd like to start a new thread for this and put a link in the first post for this thread to provide background to what we're talking about.
