clio 182 black /gold
This is a strange one but can spark plugs go rusty? I have had the garage on the phone and they said someone has changed one plug but the other 3 are rusty. I thought plugs are not due till 72K or 5 years. The first two services was done by Renault and i had a intrim service for the MOT. This was done in Feb. I wonder if they have tried to change them and ruind them. What orginal plugs should be in when the car is new?
