Do not drive or you will burn up (ruin) your catalytic converters. Computer is putting so much fuel through that it is getting to your catalytic converters unburned and the heat there is melting your converters. Look for a misfire issue

I 2nd that! Do not drive it! Likely you have a coil that is bad on top of one of the 6 cylinders.
