Hello, have you checked the fuel injectors on the fuel rail. Unplug one injector at a time and see if the miss stays the same or gets worse. You should be able to find the bad injector if there is one. It sounds like you have a injector problem. Another possible problem could be a valve problem. If you have a vacumn guage find a vacum source, and install it it should be steady, and not flucating.
