P0420 means "catalyst system efficiency below threshold on bank 1" meaning downstream O2 sensor on the left side is reporting fluctuating O2 levels after the converter.
Aka converters not doing its job.

Went to add a little coolant to the reservoir and added green coolant vice Dexcool. Realized my mistake and used my hand vacuum pump to extract the coolant and realized that the bottom of the tank was pretty nasty. Used a dowel with shop rags and my vacuum pump to clean out the bottom of the tank. Once it was all cleaned out I filled it back up with Dexcool.
