Co oznacza ten kod błędu?
The engine misfires on cylinder two during the first revolutions after starting, in a way that affects the exhaust emissions. The code indicates that cylinder two is misfiring, and it can be checked while the engine runs. The causes lie in the injection, the fuel and the intake.
