I have seen this problem before. It sounds like it could be the fuel pressure regulator. They are typically located on the fuel rail. If your car is blowing black smoke and missing and is hard to start, that is a good indication that it might be the problem. You can test this by getting a fuel pressure tester and hooking it to the fuel port on the fuel rail. Turn on the key (do not start) and it will build pressure. If the pressure drops off, it may be the fuel pressure regulator. It's a cheap and simple fix. A vacuum line and a bolt is all that holds them in.
