Many things can cause the engine to run rough. First, has the check engine light come on? Have you checked for vacuum leaks, has the fuel pressure been tested? Finally, as far as the oil, do you see blue smoke coming from the exhaust? Are there any leaks that you see? And, is this the 5.4L V8 or the 4.6L V8?
