Misfire and DTC P0455
I am wanting to see if someone could steer me In the right direction, I have a 2016 tahoe LT with a 5.3L.
I have been dealing with code p0455. The vehicle has just hit 76000 miles runs good, It does have a misfire when I am at an idle or in gear at a red light. Just started doing that after check engine came on I replaced the spark plugs on vehicle,
it is running better after spark plugs where replaced but the engine light is still on,
there is no fuel smell in cab or under vehicle
i know there is a sensor or maybe a relay that may need to be replaced i don't know any ideas?

Follow the troubleshooting here. Probably a leak in your EVAP system.
