Hi im kevin this code is a tricky one to diagnose as its not the most direct .it can be anything that causes a cylinder missfire . The first thing to do is have the engine cylinder compressions tested if all ok then the fuel injector correction status will need to be monitored to ensure injectors are in spec and replce any that are outside range .a diagnostic machine will be needed.injectors are a common failure and is likely the cause
