Rough Idle HDI
|
05-05-2016, 09:16 PM
My 306 HDI sometimes has a very rough idle I can watch the rev counter flutter up and down slightly when at traffic lights etc. This happens when the car is fully heated up. It also seems to catch/hold revs for a second just after 1000rpm when coming to a stop. The airflow metre is unplugged.
Any advice? Thanks

I have had that for quite a while. Sometimes it seems temperature related sometimes other stuff. I think it maybe the throttle position sensor.

To be honest it doesn't bother me, I would just like to know what it is to set my mind at ease.

I'd put my money on Fuel Pressure Regulator.
But get the MAF fixed too. |
