Nah is all good. this just happened to one of our outta state customer. he took it to 3 different Mitsu dealers. They told him it was injectors and tune and cables and plugs and blah blah blah. He brought it over and in 15m he was fixed. so don’t let them tell you is injectors if you got spark... but I would swap coils with a buddy. I tell ya is a coil.
to solve missfire problem then always check plugs and check coils before anything else, coils are a simple fix. 10 min job on your own. might be a good time to change for the 4 coilpack option,

I just told my tuner 2 weeks ago that my evo sounded like a WRX. He laughed at me and told me to check my plugs. While I was doing that, I decided to do a compression test and found cylinder 3 had 90 psi. I paid his shop to do leak down test and found cylinder 3 intake valve was leaking back into intake manifold. So I pulled my head and dropped it off at machine shop.
Look at post #198 for my exact words.
