What do I all need to clean the throttle body? 2014 Tahoe

You can just look at the numbers or run a graph. The upstream sensors should move up and down constantly once warmed up. The downstream sensors don't move much, change position with different throttle positions and stay put pretty much. If a downstream sensor moves like an upstream sensor, that's the sing of a bad cat.

There are lots of videos on youtube showing this.

Man, thanks for this info. This is what I was looking for.

Cleaned mine also! Checked that off the list. Waiting for AutoZone to open tomorrow to see if they have a throttle body gasket.

Then I’m gonna take a wack at that.

There is a hole already where the sensor mounts

Weird. Wonder why he drilled a hole before the cats?

Idled right back where it normally does

Maybe that vehicle did not have a pre cat 02 sensor
