N53 E92 330i
Hi guys. I picked up a 330i e92 running perfectly. The next day on a cold start the car started to judder and is now rough idling with the codes p0305 p0306 and p0300. Checked coil packs and spark plugs. No oil leaks anywhere. Service history says fuel injectors were inspected and changed about 10k miles ago. Coil packs and spark plugs changed last year. Took it to someone who said it could be the timing chain due to the p0300 random misfire code. I was suspecting injectors but it doesn’t make sense. Anyone have any other opinions? Would really appreciate any feedback.
