Hey folks, while I try to accelerate my car from 30 mph on a ramp to get on the highway, the car stutters and has sluggish gear change and it has thrown codes a few times. Dealership said it was oxygen sensor issue and in the past they have changed approximately 3 ignition coils for the same thing.

After all this work, car still tends to have hiccups which feels like it's sluggish gear change. Doesn't throw a low power mode code anymore. Unable to enjoy this car like I used to.

I took it to the dealership and an error code popped up which they fixed and it doesn't really sound like it was a fix. They swapped ignition could from one cylinder to another and moved spark plug from one cylinder to another as well and cleared the code. Car still drives like before but just doesn't have a code.

Is this a normal thing for bmw to do?
