I suggest you get the codes read. That could cost around fifty quid at a garage, or you can buy code readers from three quid at that well known auction site.

That'll give you an idea as to where to start looking.

This has got to be the infamous Nissan Micra K12 stretched timing chain - the subject of countless threads on this forum and all over the t'Internet.

As the chain stretches (what ever happened to Reynold's Chains?) it's going to put the crankshaft far enough out of position to cause the 'Crankshaft Position Sensor' fault, according to posts on some of those forums.

So the majority opinion out there seems to be to fit a new timing chain. I wonder if soaking the new chain in melted wax lubricant like I used to do with my bicycle chain would help? We used to buy a large round tin of solid wax chain lubricant which we melted on the cooker and soaked the chain in it for a few minutes.

If they are going to fit chains instead of belts, then in my humble opinion, a chain should be made to last the life of the car, not fail sooner than a belt! Even on the old Minis, we used to change the chain for a duplex one. Time someone produced a duplex conversion for the Micra!
