Have you changed the coils at each misfing cylinder? I had a misfire on cylinder 3, running really rough with flashing check engine light when engine was warm. The Check Engine light did come on solid after the misfire cleared. Swapped the coil with another cylinder and the misfire code followed the coil, so I replaced the suspect coil with a known good one. Voila, problem solved. My vehicle is a 2001 Jetta 1.8t, and from what I've read on the internet, failing coils is a very common problem. Good luck.
