Peugeot 1007 Jerking Stalling

Whoa, sounds frustrating! Jerking, check engine light, stalling... not good. Could be a lot of things, honestly. Have you checked the intake manifold sensor? Or maybe you've got a gasket leak somewhere in the manifold system itself? Is it throwing any specific misfire codes? I mean, a leak could definitely cause those symptoms.

Manifold sensor, eh? Is there a simple way to check that? I mean, without ripping everything apart? Or how would I spot a manifold leak, assuming that's the culprit? I'm not seeing anything obvious.

Well, checking the sensor can be tricky without proper tools. As for the leak, sometimes you can hear a hissing sound, but it's not always obvious. Given all those symptoms, especially the stalling and error codes, I'd bet on a significant manifold issue. Have you considered getting it checked out at a workshop? I hate to say it, but it might save you a lot of time and frustration.

Thanks for the advice. Took it to the shop, and you were spot on, the intake manifold was defective, apparently scorched. Cost me 1180€ to get it all sorted. Appreciate the help!
