M3 E90 hesitant at take off....

Hi guys,

I noticed in recent times that the M3 is hesitant when takeoff and it also kinda blips (miss) at idle. What could be the problem? I've already changed the plugs last year.

Actuators?

Possibly actuators, otherwise there is also a fuel pressure valve under the intake which goes bad after a while. Other culprits could be the O2 sensors sending the wrong feedback to the ECU impacting on fueling.

I've got faults on my car for both banks of O2 sensors, also a bit of a miss on idle, so need to spend M Tax in the coming months to resolve these....

Thanks, what about the coils?
