i got my couputer scaned and the bank 2 #1 and 2 o2 sensors are havin problems. and there is a multi engine misfire. how do i get the light off and correct it? is the misfire bad for the engine?

Replace the bad o2 sensors, and rescan the car to see if the multiple misfire is still there. If it still misfires persists, try a good tune up. What engine??

engine is an LS1.

The LS1 uses individual coils, so multiple msfire could be caused by a bad ignition/spak control module, or a fuel delivery problem.
