Gol G6 com falhamento

Hello YouTubers, here's a very important tip about engine misfires. The engine was running on only two cylinders. The scanner registered a misfire in two cylinders. The check engine light came on immediately after starting and then started flashing. Replacing the spark plugs solved the problem. Here's the pinout for this vehicle's ignition coils: 1 - negative 2 - pulsation coming from the module 3 - negative 4 - positive (post-key).
