1998 1.4 petrol - High idle speed - Neboshman
Hello,
my 306 is often, not always idling around 1600-2000rpm. I have taken it to my usual garage who diagnosed Idle Control. They replaced the idle control valve. The idle speed is still doing the same thing.

I spoke to Peugeot who say this is a common fault with the 1.4 and 1.6 models and that with these problems they have encountered before the throttle body has had to be replaced.

Can anyone tell me if this expensive and if the information Peugeot have given me is correct?

My garage said no ECU fault codes were showing so does this mean the ECU is OK or should I be more worried?

Thanks All

The throttle bodies can distort and jam the butterfly - not common though.

I'd check the coolant temp sensor and for any air leaks before doing anything else. Also bin any NGK plugs and Sagem coilpacks found loitering in the engine bay.

I had the same thing on mine and it turned out to be nothing more than the coolant temp sens... changed that and it was fine...

Thanks for the responses guys.

I looked in my Haynes manual for coolant temp sensor. My 306 has air con and according to the Haynes book the temperature sensor goes to the dashboard temperature gauge.

Can anyone shed a bit more light on this please?

Thanks
