After 31/2 years of trouble free motoring, one morning this week i started the car to find that the idle was very rough, hunting from 500 to 1200 revs.
Drove the car 6 miles to work and was the same, and the same on my way home, first though was injectors.
Car has done 122k and to my knowledge these have never been changed.
Then i remembered a few days before i had topped the oil up by 1 litre and not run the car since.
Checked the oil filler cap and it looked ok, twisted it open, then closed it again and car is now back to normal

PHEW!!

Might indicate the PCV valve in your valve cover is on the way out. Then again, youve cured it so keep calm and carry on!
