CEL codes for lean banks 1 and 2. Do I have a vacuum leak?
New to me 2004 X3 3.0 came to me with a check engine light on. I scanned it and had codes for lean bank 1 and lean bank 2. I checked running fuel trims and they were about 24 on each "bank".

I thought this might indicate a vacuum leak. Wondering if this is a common issue and if so,....where I might look first.
