Hi all

I have a 2003 manual 2.0 petrol 307. For a long time I have had the anti-pollution fault come up, with the codes indicating an o2 sensor issue. When I start the car, particularly when it's cold, the car judders violently at idle and feels like it's going to stall, but doesn't (sometimes it does when I try to actually move). It seems to be worse when the A/C is turned on.

This morning driving to work it did this, with the added feature of the throttle sticking for a second or two after I lifted off the pedal. If anyone has any hints as to what could be causing this I would love to hear them!

Thanks

Get a proper peugeot diagnostic carried out. Make sure all engine ecu software is uptodate, make sure the plugs are good, if not change.
Oxygen sensor faults can be caused by lots of thing. An indepth diagnostics is needed.
