I bought a BMW 3 series 8 months ago and since the last 2 days it has been idling very low, I noticed the previous owner put a K&N air filter on it and I do not have the factory air unit, there is a cold air intake going from the bottom of the car to the K&N air filter.
I have tried changing the idle control valve and mass air flow sensor but still the same problem. Please tell me what can I do.
