Heres the deal, 96lx 4dr with b18b1 swap greddy 18g turbo kit with fmic. running rc 310's and the shitty ass greddy blue box. I'm throwing codes(miss firing in cyl.1,3 and 4)(not second?) I changed the plugs to NGK Brk7e gapped them at .3. Took the car out and the codes were gone for 5 min then they came right back. Checked the plugs and they were white ass shit. So i bought new ones. Check the coil it was fine. The wire, cap and rotor are new. Put the new plugs in started it up it was idleing for 3 min and the codes came back.
1. Waht should i check next?
2. What could it be?
 
its probably the POS blue box. throw that thing in the trash, get some 450 DSM's and uberdata, and get TUNED, not hacked
