Default Misfiring.

Just did a header, water pump, opti, plugs an wires install. I probably drove the car about 100 miles already without any problems, an today i was out, an i hit the rev limiter once, an then a few mins after that it was mis firing...

I can put it in drive an it kinda shakes n stumbles. It starts goods, an idles kinda funny but hard to notice it.

Any idea what happended?

Sounds like you torched a plug wire, it doesn't take long and I think everyone goes through it after their first header install... Did you do OTVC wires or stock location? You really have to be careful about keeping the wires as far off the primaries as possible.

What brand opti, plugs, and wires did you use? How old is your coil?

Its a GM opti, TR-6 plugs and MSD 8.5 wires. The coil hasnt been replaced to my knowledge.

Iam going to go double check everything tonight, and if i did burn a wire.. do i have to buy a whole new set or can i buy a single from somewhere?

When I burnt my first wire, after my header install, I called MSD and they sent me a replacement wire for free, this was two years ago. Just call, the worst the can say is no, but I think they will hook you up.
