Vibrations at Startup 850

It might have something to do with the fuel enrichment conditions. Are the spark plugs of correct heat range? When was the last time they were changed? I'm no full injection wiz, but I also ponder the warm-up time/heating of the O2 sensors, that is if ratio monitoring does occur at this point. When is the fuel vapor canister purged? It might also have to do with pump-up of the hydrolic lifters, which if not receiving enough oil, will not fully actuate the valves.

Take this with a grain of salt - all things engines is a "sparetime" hobby of mine, not a career :-)
