Passenger side running rich

My 97 gt has been running rich only on the passenger side. I can smell it out of the one side and replaced the spark plugs and it only took about 100 miles until they were totally black. The driver side looks great though, even possibly a little lean. Any ideas?

I will also replace the o2 sensor because they are probably stick and should be replaced, but I thought if there was any problem with the sensors, that the check engine light will come on. Is that true?
