Twingo engine misfire

Hey, my 2014 Renault Twingo (gasoline) is acting up at 77157 km. Engine's running unevenly, check engine light's on, and it jerks when I accelerate. Error memory says misfire. Thinking crankshaft sensor, ignition coil, timing belt, or fuel pump? Could an exhaust leak cause this?

I've got a Twingo too (can't remember the year). I had similar misfire and jerking issues. Any weird noises from the exhaust? A leak could mess with the air-fuel mixture and cause those problems.

Thanks! I haven't listened specifically for exhaust noises, but I will. Was the exhaust leak definitely the cause of your misfire and jerking? How did you diagnose it?

I'm no mechanic! I took mine straight to a workshop. The mechanic said it was a leak in the exhaust manifold. I'd get it checked out professionally.

Thanks for sharing! I'll book an appointment with my mechanic. Estimate is around 265€. Hopefully it's a simple fix.
