Everest engine misfires

I'm having a headache with my 2006 Ford Everest, gasoline engine. It's got around 180k km on the clock. Recently, the engine's been running rough, and the check engine light keeps popping up. I'm also noticing some jerking when accelerating, and it feels like I've lost some engine power. I scanned the OBD and it's showing combustion misfires. From what I've read, it could be a defective fuel injector. Anyone else had similar issues?

I had something similar with my Everest. I'd check the fuel pump and also give the throttle body a good clean before jumping to injectors. When was the fuel filter last changed?

Thanks for the quick reply! The fuel filter was changed about 30,000 km ago. The fuel pump seems to be working, and I've checked the fuel pressure, which appears normal. However, I haven't checked the injection valves themselves. Are there any tricks?

My problem was similar and it was the injectors in the end. Before I got to swapping parts I got the fuel system professionally checked. If you're seeing misfires and have checked the basics, then I'd consider taking it to a workshop to be sure.

Thanks for confirming. It turned out to be a defective injector, as suspected. Replaced the faulty injector, and the engine runs smoothly now. All in, the repair set me back 515€.
