Car in excellent shape. I had a muffler replaced at an independent shop about a week ago. Less than an hour after picking up the car the Check Engine light, VSC ligth and 4WD light came on. The dealer says it is a bad "A / F SENSOR (BANK1 SENSOR 1." Can the replacement of the muffler have caused, be related to this problem? I appreciate your suggestions. Thank you.

no, the muffler is in the back of the car and the o2 sensor is in the front.
