Runs fine when cold and no misfire and even when its misfiring still runs strong with the misfire.

Spammer?

If you are a real human, try and lay out your post in a question format with some of the steps you hav taken to correct the issue.

Spammer....me??

Anyways I've changed the plug ngk, wires ngk, dizzy cap and rotor. It's a 1989 s13 with a ka24de swap with headers and straight thru exhaust.

I wouldn't worry about it unless it affects the performance / driving characteristic.

A misfire can be related to all sorts of issue, from lean condition, improper gap, wrong plug wires, exhaust gas contamination (hmm. Headers + straight exhaust).
I bet there is a 51% chance if you re-installed the OEM exhaust it would stop.

Ok Thankx!! :-)

I been thinking also could it be that also I don't have a heat shield on the headers and the stainless steel headers are getting my wires to hot???
