Seeing P0304? It means a misfire has been detected in cylinder 4. In other words, the air-fuel mixture inside the cylinder isn’t burning properly - or isn’t burning at all.⁠
⁠
Common signs:⁠
⚠️ Check engine light⁠
🚗 Reduced engine power⁠
📳 Rough running or vibrations⁠
💨 Increased emissions⁠
⁠
P0304 shouldn’t be ignored. Continuing to drive with a misfire can lead to bigger and more expensive problems, and increased emissions could even cause your vehicle to fail an emissions test.⁠
