so last week i threw two codes, one was p2187 and the other was p0300. the 2187 code was easy, I just replaced the purge valve/solenoid and that code went away. However, im still getting the misfire code. i do have step colder plugs, but I am fully tuned and the plugs have around 25k miles on them and they look and are gapped fine. I am told that it may be my coil packs needing replaced. is this correct? anything else I should do?
