Partner stalling rough idle smoke

My 2004 Peugeot Partner, gasoline engine, stalls at idle and has increased fuel consumption. The check engine light is on, and it smokes when accelerating. Could this be a defective LMM, and is it a DIY job?

I also own a Partner. Sounds like you might be having similar problems to what I experienced. I had issues with rough idling and the engine just felt… off. Did you check your air filter? A dirty filter can mess with the air intake and the air-fuel ratio, which could affect the mass air flow. Just a thought!

That's an interesting point! The air filter is something I haven't yet investigated. Were your symptoms identical to mine, with the increased fuel consumption and smoke during acceleration? Did the air filter resolve all the issues?

I didn't have the smoke, but definitely the stalling and rough running. Changing the air filter helped a bit, but it didn't completely solve the problem. Eventually, I had to take it to a workshop. They said it was the mass air flow sensor itself was defective. So, yeah, maybe get it checked out properly.

It seems a trip to the workshop was inevitable. After diagnostics, the workshop confirmed the mass air flow sensor was defective and replaced it. The grand total came to 365€. Hopefully, this will resolve all the issues!
