Jumpy poor starting high fuel consumption

I had a similar issue with my Citroen Jumpy. Sounds very familiar. Have you checked the throttle position sensor and the air intake? Sometimes just cleaning the throttle body fixes it. A defective accelerator pedal module could affect the control valve and fuel efficiency.

Thanks. I haven't checked the throttle position sensor or air intake yet. Can you explain how you diagnosed your issue? Were there specific readings or tests that pointed to the accelerator pedal module?

In my case, the diagnostic tool showed inconsistent readings from the throttle position sensor, even after cleaning the throttle body. Also, the idle was erratic. Considering your symptoms and the age of your Jumpy, the accelerator pedal module might be failing. Get a professional diagnosis before replacing parts to save money and time.

Thanks for the advice. I took it to a workshop, and you were right. The accelerator pedal module was defective. The repair cost 205€. Your information was very helpful!
