Clio 182 over fueling

[Vickys1989]

Hi there,

Need some help. Last weekend I started my 182 and it had a misfire and stank of fuel took it down the road and it chucked loads of white smoke out and then ran fine.
This week it has been quite lumpy sitting still (more than normal but no misfire) and has been smelling of fuel and chucking bit white smoke out. My MPG has dropped from 38 to 31 and my petrol is vanishing.
Does anyone know what could be causing this ? I have no lights on dash and don't have clue were to start.

Thanks,
Vicky

Pre cat O2 sensor is probably the likely culprit.

Around £60 for a Bosch LS6046.

If you post a rough idea of location, one of the local guys might have a code reader to get the live data… dead sensors are pretty easy to see if the codes are up.
