Could this be right?

Surely I would of experienced some sort of symptom?

One of these should fix your code 13 issue.

Maybe worth asking if anyone is doing an order imminently to add it on. Mike may also be able to supply these, otherwise I'm sure the connector will be common to many other applications and be widely available.

 

Thanks Joel.

I think it's the same as the IACC one, that plug is common through most Nissans from that era, Almeras etc

 

Thanks Steven.

Nothing to do with the error code 13 i know, but as Joel suggested, I have been cleaning connectors etc'

As I was at it, I thought I would check the resistance of each injector just to eliminate them.

Readings ranged from 12 ohms to 12.4 ohms across all 6, so as I understand it, all are good?

Nicely cleaned and greased now.

Still searching for the cause of my intermittent misfire, I decided to check the resistance of all 6 coil packs.

Guess what, they passed with flying colours, so still none the wiser.

I even swapper them all over from left to right to see if the issue moved with them, but no change.

Stumped at the minute.
