So work got nuts on Friday night. 2 of my drivers broke down out in Harrisburg PA, 30 miles from each other. The CO car was in the shop for routine maintenance. Jump into my Tahoe to get the guys that are stranded without a way back home.

Trucks are repaired and I head out again in the Tahoe with my drivers to get the trucks back to the office.

Now my Tahoe is throwing codes. P0158 code and running like shit. It’s pissing rain out and hot as hades! Perfect!

I’m pretty sure it’s a 02 sensor? Can anyone tell me which one? Post cat which side, are there anything else that could be throwing the code?

Mother f-in piss bucket. Suck ass weekend that I was supposed to have off!

No good deeds go unpunished! I am in Pa. Where are you? Remember you are an essential worker!

Just stopped at Cabellas in Hamburg. Used 1/2 tank of gas from Harrisburg! Gonna grab lunch calm down a bit maybe look at a new hand cannon at Cabellas and finish my ride back home using another 1/2 tank of gas!

Bank 2 sensor 2. Is... passenger side post cat?

Washed mine....got back yesterday from a weeks vacation, but about 2K miles on the truck and it did great. The ceramic wax held up awesome through the rain, puddles, salt spray and bugs. It all came clean pretty easily.

Yessir. Might be the cat itself though. You can swap the downstream sensors and see if the code follows. If it doesn’t then it’s the cat.
