Customer Question

I've a Peugeot 406 Saloon Petrol 1999- 1.8. I recently experienced a very high erratic idling that increases the rev counter substantially to a TR/Min of 40 on the dash board. This occurs immediately after starting the car and this high revs continue right through my journey. Two electricians advised me to replace the idling air valve but after replacing it with a new genuine Peugeot part the problem sounds worster(TR/Min.40). What possibly could be wrong? Would appreciate if you could come up with some ideas.

Hello, welcome. My name is Mike, I will do my very best to assist you with your question. I apologize if you have been waiting long for a response.


Are there any type of warning lights coming on?
Customer: replied 2 years ago.

I apologize for only responding now. There are no warning lights coming on at all.

Expert:  Mike Kelly replied 2 years ago.
Ok. The issue that you are having is consistent with a throttle body issue. It can be either the throttle position sensor causing the issue or the butterfly valve inside of the throttle body sticking. The first step is to have the throttle body cleaned if that has already not been done.
