Ok my wife is out with the car she called me and said..

It sputtered shortly them the SES light blinked and stayed on.

I just had headers put on so i am thinking it is a plug wire

what is the best way to go about checking all the wires?

 

1. Make sure the wires are not crossed
2. Make sure no burnt wires
3. Make sure all of the wires are pushed all the way in on the opti, coil, and plugs
