p1153
bank 2 sensor one which is passenger side precat (I have longtubes and have rears tuned out) this 02 was recently replaced and not for this code ( it wasnt working correctly during the second tune)
I just recently replaced the plugs, and I did read that this code can show up due to a missfire? Wouldnt the system also throw a missfire code as well? Is there a way to confirm if its a missfire? I maybe answering my own question here but is it possible one of the plug wires isnt on all the way and that could cause this?
This is the second lengthy drive (10-15 minutes) its had since I changed plugs and this was the only code in the system, and I dont think I have had this code before. so Im curious if I should just clear and see what happens or if I actually have another issue

Think I may have figured out my issue I'll edit this post after I swap out the plug wire for future reference
I guess the fire pulse was being limited/lost with the exposed wire resting on metal, so it was running on 7 cylinders, since the cam lope is so heavy I never even noticed at idle and looking back I should have noticed when I was driving it. It seems to be fixed now and the wires are re-routed so they dont make contact with the headers any longer
I had a talk with a friend who is a mechanic and he explained a few things about how the flow of checks for a misfire works. im not sure if I have the numbers exactly right but its the general jist of it that people likely need to know.
say the 1153 code pops and you dont clear it. I think it was between 400-600 more checks/cycles do determine a misfire, from there its another series of checks that determines which cylinder/coil. But the process(counter) starts all over if you clear the code. If you are someone like me who rarely drive the car and just clears the codes you are essentially shooting yourself in the foot not letting the ecm do its job and narrow down the fault in my case.
