Peugeot 307 Engine Issues

Sounds familiar! I had similar issues with my Peugeot 307. Rough running, stalling... the whole shebang. Have you checked your ignition system? Specifically, the ignition coil and its connections? It could be a misfire. Are all spark plugs ok?

Ignition coil, huh? Where exactly should I be looking for connection issues? And could a faulty plug really cause all that mess?

Think of the ignition coil as the heart of your spark. A dodgy connection there is like a kink in an artery. Yes, it can cause a lot of mayhem! While you can check the connections visually, tracing the exact fault without proper tools can be tricky. I'd recommend taking it to a workshop if you're not confident.

Cheers! It was indeed the ignition coil. Bad connection, just like you said. Cost me 95€ to get it sorted. Runs like new now.
