Ranger knocking combustion

My 2007 Ford Ranger with a gasoline engine is having knocking combustion issues. Mileage is at 38090 km. I've noticed reduced engine power, jerking when accelerating, and some smoke. Error memory also stored a fault. Could deposits in the combustion chamber be the problem?

I had similar symptoms with my Ranger! Detonation and pre-ignition can really mess things up. Any chance you've been hearing something that sounds like piston slap, especially when the engine is under load? Does the smoke smell particularly bad?

The smoke does seem to have a stronger smell than usual. Piston slap, I'm not sure. But the engine knock is definitely there, especially when accelerating. What did you do about it?

Sounds very familiar. Based on those symptoms, and if you're not comfortable tackling engine work yourself, I'd strongly recommend a visit to a reputable workshop. Knocking combustion can lead to serious engine damage if left unchecked.

Thanks. Ended up taking it to the workshop. They confirmed deposits in the combustion chamber. Cost me 425€ to resolve.
