Customer Question

I have ODBII codes P0171 and P0102. The car sometimes stalls after driving it for a few miles. Is it the mass air flow sensor?

The most common problem is the mass airflow sensor. Unplug the mass airflow sensor, take for a drive to see if problem stops, if so then replace. You can also try to clean before replacing, they sell mass airflow sensor cleaner at the parts store. If it still stalls with sensor unplugged then let me know and we will go over some other possibilities. Thanks.
