00 1.0 Strange Juddering - AlfistiMatt
Hello,

My sisters K11 Micra was originally struggling to start, and having confirmed the battery wasn't as fault (changed with another working battery), we narrowed down the fault to possibly be Spark Plugs, Distributor or Rotor arm.

So we thought we would just swap it all over.

Put it back together and it started on the button, we thought it was fixed.

Then after driving to work, the car started juddering at any speed (with the Engine light temporarily lighting)

I had another look at the car this morning and started to reverse some of the work, to find the dodgy part.

- Spark Plugs - Swapped with old and was exactly the same
- Distributor Cap with another old part we kept, not the one we pulled out - Juddering stopped

We then went on a 30 min test drive without fault and just as we were approaching the house it juddered (quite harshly).

The only thing left now is the rotor arm, but I am surprised the Distributor Cap made such a difference, as there is still a fault (not there previous to the non starting)

The HT leads all appear in good condition and the car is a very well maintained example.

Any tips would be much appreciated.

Regards

Matthew

sounds like the maf sensor. ie replace the throttle body or if possible just the maf and this should be ok then. its a commen fault on micras
