I know it sounds like a stupid question but did you plug in the O2's? Or did one get damaged? That would cause a miss. During the install did you put new plugs in?

none of the plug gaps got smashed did they? and just for ha has.....while putting in the headers you didnt unplug the main harness for the ignition coils, and if you did, you plugged both sides back in.....sounds retarded but ive seen that happen

the plugs never came out, they are only a few thousand miles old, and never got in the way,the wires are new, because we ripped one getting them off.

i checked the main harness, and they are brand new o2's but im gonna go check to make sure they got plugged in right or something liek that, im not tripping a code for a primary o2

i had this same problem after my header install and i sprayed water on the plug wires while it was running and kept hearing arking so i put new plug wires on and it was fine after that!...Also make sure you bought the right o2's that could cause a problem also!

if you didnt pull the plugs make sure that you didnt crack on this will cause an arc you wont hear put will cause bad miss more so when under a load

You probably cracked a plug. Thats what exactly happened to me with my old 96 3.8l Camaro and I was having the same symptoms as you.
