alright i am not going to write a 9 page article but i will say the basic facts and see what you guys think. Sat., went to the dyno to see what the car would do on the TNT kit, first run we went NA for a baseline, the car ran fine. the guy shut it off to check the straps and went to go for the N2O run and the car starting missing as soon as he started the engine. I took the car to auto zone to use their code scanner and i am getting p0300(random misfire), i then take it to a buddies house with auto tap and the bank 2 o2's are inactive so i replace them. no help still missing. next i hook it up to a mac mentor to see what is missing and it is coming up that cyl 6 and 8 are missing that is it and the o2 are still not moving on that bank. i am straight up confused now i checked the ground in which all 4 o2 and the 4 coils on the right bank share. but the way i see it is if the ground was messed up then all 4 coils and all 4 o2 would be messed up. right now my hands are in the air with the whole thing. any help would be appreicated. thanks kevin

Sorry but I thought when I read your post you meant your engine was gone!
Only thought that because this is the External engine thread.

I'll let someone that may know how to assist you answer this.

Good luck hope you find what is causing the miss.

I'm not a pro by any means, but by chance, did you pull a few of your plugs and just check them if you've been running nitrous?
