Hey guys so I have a 2009 bmw 335i with 94k miles with a jb4, downpipes with vrsf dp fix, chargepipe with bov, and dci. I have replaced spark plugs to ngk 95770 gapped to .024 with 5k miles on them now , brand new Bosch coil packs, new index 12 injectors coded correctly with 5k miles on them , and a new vcg with 5k miles on it . The problem I keep having is that whenever I start the car in the morning the cylinder 6 keeps misfiring for about 2 mins max and then runs absolutely flawlessly. This happened on every cold start when the car hasn’t ran in over 4-5 hrs. I thought it was my coil packs at first and since that was the one thing I hadn’t changed since I bought it I finally decided to put new ones in hence those are the only maintenance items that don’t have 5k miles. I also run 91 pump gas in Cali and map 0 most of the time on my jb4 i also swapped the number 1 and 6 spark plugs to see if anything changes but it’s still misfiring on 6. I am absolutely lost and would love some suggestions
