2013 335i Sportline Sedan (stock) with 104,833 miles. I have a reoccurring, random amber engine alert. It comes and goes with no apparent pattern or cause. No change or degradation in drive-ability, performance or gas mileage Been dealing with this for a couple of months. When I run the BT Diagnostic software, all I ever get is below.

Current Fault Codes:
-118001: Mixture control: mixture too lean
-101F01: Throttle valve opeing angle, absolute pressure, intake pipe, comparison Pressure too high

Does anyone of any thoughts on the cause(s)? The randomness is making it hard to diagnosis. Thanks for any insight.
