I have a 2003 Evo 8 that I've been having some issues with. Recently when going wot my car will hiccup/misfire around 5k-6k. I changed my spark plugs and gapped them at .26 about a month ago because i was having the same issue and issue went away. Well today when giving a friend a ride my car encountered the same problem. I'm not sure if my spark plugs are bad or a coil/ wire problem . Spark plugs are NGK brp7es gapped .26. Car has 108xxx miles. If anyone has any idea i would greatly appreciate the info. Thanks
