R32 Gtst 4 Door Issues

[Armed fab]

ok everybody I have searched for this with no luck,

( please excuse my poor spelling and grammar )

My r32 is a bit of a Frankenstein motor.

History of the car

Rb30 built bottom end

Rb25 de head cams and flowed

T67

In a r32 4 door shell, running autronic sm4

Makes about 525 hp

So my problem began when I noticed a slight miss on cold mornings.

Cleaned the icv with help of the guide , all sweet for about a day .

It started to hunting after it got warm wouldn't hold idle .

So made sure it was all back together correct replaced hoses to icv

Ran all sweet , lasted for about a day .

Started to miss again

Changed the plugs they were terrible.

Ran sweet for about an hour started missing again.

Replaced colpacks with spitfires

Car still missing a idle , heaps of black smoke while idling , hunting a lot

Removed the new plugs , noticed they were wet with fuel

Plugs are gapped to .9 brand new ngk.

Just about out of ideas as to what it could be ? Any suggestions .?
