As stated in the title, my cobra is sputtering and backfiring below 3 to 3500 rpms then smooths out, it seems to me like its missing fairly bad. Its hard to tell during idle since it has stage 3 cams installed and i'm fairly new to this car so I cant say for sure. It's also worth mentioning that during WOT I haven't noticed the backfiring/hesitation and it takes off like a rocket. I pulled the plugs and cylinder 1 and 2 plugs were fairy foul but not terrible. I cleaned them all up and re-inserted them and it seemed to noticeably help for a while but not eliminate the problem. I do plan on doing a compression check, using a code reader, as well as checking the coil packs these next days off. Is there anything else I should be looking into? Any imput would be appreciated, Thanks.
EDIT: Also if it means anything to anyone. I am able to gently accelerate without any popping/backfiring or hesitation fairly well, but as soon as I give it to much throttle it starting showing those mentioned behaviors.
