So, had the new crank hub installed, VRSF Catless DPs, and colder plugs installed. On cold or warm start, the car will rough idle for a few seconds and then die. Start it back up and it does the same a few times, and then it rough idles for a few seconds and then idles smooth. Any idea what might be up? Anyone else experienced this? Maybe I need to reflash it? Searched the forums and found a few possibilities, but nothing that really pointed to what I was seeing. Thanks!
