i have a c5. when cold starting it feels like a mad kangaroo. like it wants to cut out. once warm seems ok.

Tune up time

HAHA A mad kangaroo! l love you.

Those damned Frenchies.

The engine temp sensor tells the ECU if its hot or cold to allow it to change the mixture. its probably faulty or loose. take it to the Citroen dealer.but if you want to try it yourself, go buy the sensor and fit it. 90% sure it will do your job..

put your foot on the proper pedal ya mooron

Attach a white flag onto the antenna -- it will feel more at home.
