Just got through putting in flowtech headers and I have a missfire. What could it be. Plugs are good, and the plug wires are fully connected.

Could it be that the coil packs are out of order. If so, how do I know and how do I get them back in order.

Do the plug wires have a specific plug they go to?? I just kinda mixed matched.

Help,
John

if you did more than headers if you did the catbacks..to ive heard of people accidently damaging the O2 sensors and not even know it...

Duno if this could be your problem

This is really a no brainer,if you have a miss/skip it will set the MIL/SES light, scan to see which cylinder and it will be easy to narrow down the problem of plug/plug wire/ coil conection etc.

I thought taht the wirring harness set the firing order and as long as u have the harnesses in order and the coil packs and wires is going to the plug right below it everything will be ok. even if i take a plug wire off one coil and put it on the other side. Also you could take a coil pack and move it from the pass side to the drivers side and it would be ok right?
