What If The Engine Runs Unevenly Or “Lopey”?

Hello, I'm Dave, a car enthusiast and mechanic in training. Recently, my Volvo excavator has been running unevenly, almost "lopey". It's not the smooth, consistent hum I'm used to. Could it be an issue with the fuel mixture being too rich or lean? Or perhaps something to do with the cam? I'd appreciate any insights into why this might be happening. This is affecting my learning process and I'm eager to understand and fix it!

Hi Dave,

It’s indeed possible that a “lopey” engine could be due to an improper fuel-air mixture or issues with the camshaft. It could also be a result of worn-out spark plugs or a faulty ignition coil.

I’d recommend checking these components and ensuring they’re all in good working order. Remember, regular engine maintenance is crucial in keeping your vehicle running smoothly. It’s great to see your enthusiasm for understanding and fixing the issue!

Keep learning and you’ll become a skilled mechanic in no time.
