c300 code p0422 intermittent
it shows up for few days or a week and then disappears again for a while.
i only owned this car for about 8 months
it show up twice and go away on its own.
what the hell is the function chain anyway? does that fueling ignition or oil leak problem from left side engine?
no other codes just this one.




Most of the times, from where you see oil leak, the unmeasured Oxygen will be sucked inside this chain.
