E320 wagon 1994 M104 with 180k (passed 2 years ago well within spec).

I had a vacuum line connected wrong off the throttle body (the one that goes to the valve that gets fumes off the charcoal canister).

I am wondering if there is anything else I should check before going in for a retest? Not certain on exact oil consumption, but have some.

I can't get current registration till I pass smog, and I have a sticking key in ignition issue...need the current registration so I can order a matched key lock cylinder, and don't want to start/stop the car a lot so the key doesn't get stuck and need to take apart dash...etc.

Any help MUCH appreciated! :-)
