Peugeot 207 uneven running jerking

Hi, I'm having trouble with my Peugeot 207 (2007, gasoline engine). It's got 75722 km on the clock and recently started running unevenly. The check engine light comes on and there's an error stored. Plus, it's jerking badly when accelerating. I've checked the spark plugs and they seem fine. Could it be something with the crankshaft sensor or even the timing belt?

Hey, I had a similar issue with my 207! Check engine light, jerking... sounds familiar. Did you check the fuel injectors or the oxygen sensor?

Thanks for the quick response! I haven't checked the fuel injectors or the oxygen sensor yet. Was your issue exactly the same – uneven running and jerking under acceleration? What was the cause in your case?

Yep, exactly the same! Turned out to be a leak in the exhaust system. Honestly, I'd recommend taking it to a workshop to get it properly diagnosed. Saved me a lot of headaches.

Thanks for the advice! I took it to the workshop as you suggested, and you were spot on – a leak in the exhaust system was the culprit. Repair cost me 265€. Appreciate the help!
