Ok so i have an evo ix and one morning i started the car and it had a huge misfire problem, checked the plugs two were bad so i replaced them. then i went to start the car and still have the misfire problem. so then i found out one of my coils was bad so i replaced them with the OKD coils, then i started the car again and one of the coils started to smoke and was really hot!!! so i think my engine wire harness might be messed up some where??

Are you running a Twin Power DLI, by chance? When mine bit the dust on my 8, it ended up being that; bypassed it and it stopped eating coils, until I replaced it. Faulty unit I'm assuming.

Of course, if you're not running one... nevermind

I had a coil imploded on me before. Found out it wasn't grounded properly. Check the harnesses to see if it's connected to the chassis or the block.

check the harness for loose grounds, loose connections or fried relays

ya i have the HKS DLI on there but i took it off when i started to have the problem, i also started taking apart the harness everything look good and i ran new power and trigger wire not ground and it was still misfiring. i guess ill have to try the ground too! i was also thinking it could be maybe be the injector driver or maybe the ecu is taking a fart?
