Ford Flex engine misfires

My 2011 Ford Flex with a gasoline engine has 177221 km and is now experiencing combustion misfires. The engine runs rough, the check engine light comes on and off, it jerks when accelerating, and engine power seems reduced. Anyone else had this happen? What fixed it?

A 2011 Ford Flex is experiencing engine misfires, causing rough running, intermittent check engine light, jerking during acceleration, and reduced power. Possible causes include faulty fuel injectors, a malfunctioning fuel pump, or issues with spark plugs and ignition coils. It is suggested to read error codes and consult a mechanic for a thorough inspection to identify and resolve the issue.

I had similar issues on my Ford Flex. Have you checked the fuel injectors? A bad injector can cause misfires. Another possibility is the fuel pump not delivering enough fuel. Spark plugs and ignition coils are also worth checking. Have you read the error codes?

Thanks for the ideas. I've thought about the fuel injectors, but haven't looked at the other things you mentioned. When you had the problem, did the error codes point directly to the fuel injectors, or were there other codes too?

The error codes showed a misfire in a specific cylinder, which turned out to be a faulty fuel injector. Given your symptoms, I'd suggest taking your Flex to a trusted mechanic for a thorough inspection to find the exact cause. My repair cost 515€.

Thanks for sharing your experience and the possible solution. It looks like a workshop visit is needed. I'll post the resolution once it's sorted out.
