Vectra 04 - petrol fumes - wonderwheels
Over the last few weeks I have noticed a strong petrol smell from my car.Mainly when in the car is stationary with the engine ticking over after a run in the car.It was in the Dealership twice and they said they couldn't fault the car and couldn't find the smell. (see www.honestjohn.co.uk/forum/post/index.htm?t=39213 )

In the last week an emission warning light came on and has stayed on.This is due to a faulty oxygen sensor.My car goes in to get this replaced next week.I think the garage will use this as the explanation for my problem.Hopefully this will turn out to be the case.Would this indeed cause this issue?
