I have a strange problem with my X18XE1 engine... If I run the engine for a short period of time (ie. to let my wife's car off the drive), then next time I start the engine it'll run on 3 cylinders for about 20-30 seconds before the 4th kicks in (and there's quite a strong smell of petrol!).
With normal use this does not happen. It only occurs after the car has been used for a very short amount of time.
Any ideas anyone?
