Hiya,

Sounds like the car is just burning off some unburt fuel,

If the car is runng good and you can see that the inside of the exhaust tail pipe is black and not pure white you should be O/K, :3gears-rh

Hope this helps

Could be fuel cut, maybe slightly over boosting!

What spec is your car?

Strange one that but |I would check/clean all your connectors on the engine inc of the AFM. Does it do this when stationary when you rev it or only when driving?
Also is this an EGI or turbo and what year, TII, FD ?
