Ok so my BMW hunts 90% of the time on idle 2krpm and back
When I remove the oil cap it stops :s excessive blow by?
Also under throttle the car surges in power, in the exact same interval as it hunts.
Which has me thinking its a sensor or something rather then crank pressure causing it?
What else should I look at?
I've seen alot of threads about surging accel being o2 related so my first step is timing belt and o2 sensor
