B1 Short Term Fuel Trim 35%
B1 Long Term Fuel Trim -3.9%
Bank 1 Too lean (P0171)
I'm guessing a large unmetered intake air leak, but Live Data shows NO reference to Bank 2 at all on my Scanner (Autel MaxiDAS 708), and
I don't HEAR an air leak between the intake air plenum and the Right Side Head Ports, and shooting Flammable Brake Cleaner around don't indicate a leak.
No Misfires but slightly unsmooth idle.
Curious WHY does the Live Data not even list Bank 2 PID?
Any suggestions welcome!
Thanks!
Bob
