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
