May have sucked some of that extra oil into the CCV (crankcase ventilation valve, or also called the oil seperator). Having fluid in this can interfere with proper vacuum and may be the reason for the rough idle and codes. Look around the valve for any excess/leaking oil.
Can burning oil cause a misfire?
An engine that is burning oil produces higher emissions. It will also fail to pass an emissions test due to elevated hydrocarbon emission. -Monitor the engine to see if it is misfiring or running rough. An engine that is burning oil will foul the spark plugs, causing it to run rough.
Can too much oil cause knocking?
And a hot spark plug or exhaust valve can also be the cause of pre-ignition and knock. Too much oil however, is not a probable cause. Filling it way to much could result in (more) oil entering the combustion chamber, resulting in its combustion there and hence knock, but I wouldn’t expect it.
Can bad spark plugs cause oil consumption?
As engines wear, the combined loss from external and internal oil leaks might increase oil consumption to one quart per 1,000 miles, which should not be a problem if the spark plugs don’t become fouled with oil ash or the exhaust doesn’t emit visible oil smoke.
