I put the old one in let it warm up cleared the codes and checked the voltage and they were fluctuating how they were supposed too til i got back and now have a p1153 code showing up?
This live data is while i took it on a drive fully warmed up
Did both precat O2 sensors keep switching the whole time you were running after the truck warmed up and you went into closed loop?
What was the post cat O2 sensor doing?

Not yet but i will get to it later on in the week. Yes both precat o2 sensors were fluctuating. The post cat was fluctuating around 700-900mV. I also got a p0155 code when i drove it today and idled like **** but didn't miss or anything
Your bank 2 fuel trims are sky high, the system is compensating for a perceived lean condition and increasing fuel delivery. We need to get that exhaust leak fixed to make sure thats not it before we go after the other possibilities so we dont chase our tails.
When your working on it later in the week pull a bank two spark plug and see if its fouled.
