The car is running. Half yellow check engine light came On. When i start the car, the light goes away for like 5 secs and comes back with message "Engine Malfunction: Reduced power mode".
Spark plugs and coils were changed in Dec 2017 but since then only 10,000 miles have been added in last 2 years.
Codes coming: P0015; P0305; P0304; P0305;
I am freaked out about the misfire code and metal shavings present in motor oil.
I read on different forums and I got to know that VANOS Bolts may be the reason as they get sheared after every two years and the metal debris falls on timing chain.
But again I am not sure.
Please advice.
