Rich afr at idle

[kakanator]

So I got my other none melted harness in and all good but my air fuel ration is super rich. Before my old harness melted my afrs were 14.2 to 15.4 at idle but now 12 to to 12.3. I checked for codes and boost leak tested today found none. Also i am getting this what feels like spark break up at 5000 rpm not sure if the plugs are bad or not gaped right. here is a vid.

so I changed my plugs and made sure im at .032. Still getting the spark break up at high rpm not sure what it is. Im going to check the ignitor first and then cps.

So today I got a chance to swap back to the stock coil packs from the vvti i have. Put them on bolted it down and took it for a drive and no more break up. So I turned the ebc up in steps and stopped at 14 psi at 12.5 afr. Pulled so hard for a stock ct with just 560cc and lex with ddp and ic kit.
