Hi all,

My Silvia has recently developed a strange problem.

It misfires and runs on 2/3 cylinders all the time its running, except when the key is turned to the off position or removed, it will then run normally for about 3 or 4 seconds before dying.

I have checked that im getting spark on all 4 cylinders, and that im also getting fuel.

I have also tried swapping the coilpacks and coilpack loom with a known working one, didn't help.

Anyone had a similar issue, or has any ideas that can point me into the right direction diagnosing this?

Vehicle spec is an s15 spec s with a s14a sr20det swap.

Thanks in advance.
