code 52, running rich

[Zed]

And my dawes af gauge verifies this, 2nd green light always on while idling. What are the reasons a stock fuel system would be rich? Could it have anything to do with a few charcoal canister vacuum line deletions? I had the CC removed completely from my last 2 TD's and it didnt do this.

Well on mine it was a blown FPR. I had 80+psi of fuel pressure all the time.

I just had that same code on my 86 T1 it ended up being the tps

Big vacuum leaks, bad 02 sensor and 02 sensor ground, stuck fuel pressure regulator, way to big injector, clogged fuel return, a big rock in front of you air filter
