My mods are in my sig. The car is missing above 3000rpm pretty bad. It misses below but not as noticeable. You can hear the exaust popping. I also smell fuel when I'm driving. I checked for leaks and have found nothing. I was just wandering if anyone has any thoughts on this. When I give it full throttle, it misses and you can smell gas real bad. Any help would be greatly appreciated!

 

Ever look under the hood at night to see if there is any arching?How many miles on the opti? replaced anything lately?

 

Just started testing ignition and found another burnt spark plug wire. These mac headers are not very forgiving. Thanks.
