LandCruiser engine misfires and jerking

I'm experiencing a strange issue with my 2013 Toyota LandCruiser (gasoline engine). It has 116516 km on the clock. Recently, the check engine light came on, and the engine is running rough. I also notice jerking when accelerating and a definite reduction in engine power. I suspect combustion misfires. Any ideas?

Whoa, that sounds rough! Check engine light plus jerking? I bet it feels like you're driving a bucking bronco. Is your throttle response also off? Could be anything, spark plugs maybe?

Thanks for the quick reply! Yes, the throttle response is definitely affected. What makes you think it could be the spark plugs? Is there anything else that might be the reason for this?

Spark plugs are easy to check first. But a cylinder misfire with all those symptoms? Honestly, that sounds like it could be a fuel injector issue. Could even be a defective valve. I think you should let a workshop take a look. Keep us posted!

Thanks a lot for your advice! I took it to a workshop, and it turned out to be a defective fuel injector, as you suspected. They replaced it, along with the injection valve. Total cost was 515€. The engine runs smoothly again.
