I have no idea what this could be. I was getting a 104B01 code in the past but that stopped. I recently upgraded the chargepipe because I felt the car struggling under boost and had codes. On warm starts, depending on how long I leave the car, the car always starts up at about 1k rpm’s then simmers down. But it also shakes a lot. Sometimes it’ll just shake. Other times it’ll start up at 1k, drop down to 500 for a split second before going back up and then starting to shake a ton. On cold starts it starts fine, simmers down a bit, and then goes back up. Could this be plugs? I’m attaching a vid of the cold start.
