2006 3i repair conundrum
 

Hey guys,
Not sure of these are related or just coincidence...
My engine light error code is system too lean at idle. The light came on yesterday afternoon. I've done the laundry list of checks... gas cap, oil cap, carburetor cleaner to check for air leaks to no avail. It's happened a year ago so no biggie. The dealership has told me before that there is a small pinhole air leak somewhere and that could explain. Today the AC started blowing hot air off and on and idling pretty rough. It also had its hesitant moments at highway speeds with the ac on. When the ac is off its smooth and easy as usual. Any ideas??
This girl is all out of them!
