…The auto shop checked for error codes and found the following: P1450 No DTC definition found, P2195 O2 sensor signal biased, and P0507 Idle air control system revolutions per minute higher than expected. The auto center suggested I take the car back to the dealer for inspection as they can not diagnose. I fear for my family's safety while driving. I feel this problem is caused by the excessive vacuum in fuel vapor management system (Recall 18S32).
…My mechanic detected O2 sensor codes P2195/P2197 indicating "stuck lean." But nothing about the brake booster, and so we cleaned it up a bit and tried to get more of an understanding of the issue.

…WHEN MY CHECK ENGINE LIGHT CAME ON A WEEK AFTER SERVICE, ERROR CODE P2195 (BANK 1/SENSOR 1 LEAN) CAME UP, AND THEN WENT AWAY. I WAS TOLD IT WAS STILL SAFE TO DRIVE AND CONTINUED TO DO SO.

MY AIR FILTER WAS REPLACED, AND 5 DAYS LATER THE ENGINE LIGHT COMES ON AGAIN, SAME CODE. I SCHEDULED SERVICE WITH FORD, AND THEY VERIFIED THAT THE ENGINE CODE AND THE STALL ARE RELATED TO THE RECALL.
