i have a 2005 bmw x5 3.0l auto with about 78000km on it, i have had the service engine soon light on for awhile now, so i got it scanned and it came back with these issues:
- Secondary Air Valve jammed open
- Mass air sensor
- Fuel Trim #2
- Misfire #5, secondary air flow

any help would be greatly appreciated

check intake boots for cuts/cracks, inspect all the vacuum lines (there are a few tiny ones at the rear of the intake manifold and at the front of the passenger side of the head.
