emission test on 1999 Oldsmobile Intrigue

my car keeps failing the emissions test. the computer reads that the O2 sensor an the erg valve are "not ready" the crankshaft position sensor has already been replaced an there are no codes being shown on the computer. the mechanic said to drive it around or take it to the dealership to see what the issue is. can i unplug the battery to reset the computer in my car?

I'd suggest taking to a GM specialist or a diagnostic specialist if you can find one. But one odd thing that could be a factor is a faulty thermostat preventing the engine from getting fully warmed up. It'd be a good idea to check the running temperature on a 'scanner,' reading engine data from the computer while driving to see if the engine's reaching running temperature. Disconnecting the battery won't solve anything. All the monitors will have to reset (ready) so that won't do you any good. Many years ago you could DC the battery and lose learned data, shutting off the check engine light and restoring defaults, but that's not the case in a modern car. Wouldn't fix anything either.
