Well the LH2.2 that you have doesn't have OBD, so multimeter it is. If this happened suddenly though I'd be more inclined to suspect the fuel pressure regulator, pull the vacuum hose off it & see if there's fuel present there. Of course running that rich may have been enough to foul the O2 sensor, and if it's pooched then pick up the Ford Mustang Bosch O2 sensor and splice in the Volvo connector; plenty of archived posts about this swap. It'll save you $$$ & work better & longer than the so-called universal non-Bosch sensors.
