545i rough idle
So my 2005 545i has a idle issue. Mostly it's at 500 rpm idling and you can wheel the car shake but some other times it's at 750rpm which is pretty regular. Now I do have a check engine light for the secondary air pump. Could that cause the idling issue or are they not related? If not related what could cause my car to idle at 500Rpm

I'm usually at around 500rpm without AC and 750ish with AC. Check your CCV Valves as well as the secondary air pump.
