Misfires after cam install

[Thatonez71]

I installed a Texas speed stage 2 cam in my 2014 Silverado 6.2 during the tuning the tuner mentioned lots of misfires on cylinders one and three and showed the 02 sensor graph line was flat. I’ve moved spark plugs, wires, coils and retorqued the rockers and the issue has not went away any ideas what this is before I tear down too far

If the o2 sensor is not switching at all, that is a problem itself and could be a reason for the poor running engine. If you swapped the o2 sensors side to side and that sensor does the same thing on the other side, then that o2 sensor is dead.

 

If the misfires continue on bank 1, then you need to check compression and leak down on that bank. If those numbers are fine, you'll need to dig into the engine more. Like replacing injectors maybe.
