Grey smoke!

[sweetyGTIR]

Help please help, ive just noticed that the R seems to let out a bit of grey smoke when driving normaly after a bit of right foot fun though and theres sometimes a pop an bang from the exhaust:lol: checked all hoses, all fine, R uses no oil or water and runs absoloutly fine, must add that theres smell of petrol at idle, i can only put this down to overfueling, could someone please put my mind at rest as it had full rebuild 4000k ago and budget and wife wont allow another cheers guys

Sounds like its running mega rich, check your plugs (they should be black if it is).

Could be a faulty or unplugged lambda sensor :?:
