Thanks for the reply Humtech!
The scanner I have reads random misfire right bank , but not which cylinder it is.
I replaced the drivers side cat with a Magnaflow universal cat. I welded in myself.
No dealer flash on ECM .
I, ll see if I can get someone with a better tech tool to check o2 sensors
Thanks
