Miss fires and bad coils generate codes, so either your ecu was reset (power disconnected) or you have some other issue. You didnt answer what PSI you tested it at, many leaks only happen at higher levels. I believe testing to 30psi is standard for most shops. Your gap is a huge red flag. Factory manual calls for .7-.8mm so right there is a huge problem.

Im not saying it isn't the coil. It very well may be the ignition coils are faulty, but there are many other things it could also be. Troubleshooting is a methodology and you have to cover the basics before you start delving deeper.
I never claimed that i could diagnose the problem with those 3 questions. The answers to those questions though are the first layer of the diagnostics, and you need the answers to know how to proceed further.

glad to hear you fixed it! I also had to replace my boots/wires a while back. Ive been eyeing a C.O.P. setup since my coils are kicking 140k miles on them and im sure they are getting tired.
