Ben called to see if he could come to the appointment early. He was nice and he installed the alternator and belts and jumped the car to get it running. I was told to leave it running for about 10 minutes to charge the battery , then I'd be good to go. I let the car run for at least 20 minutes then turned it off and it wouldn't restart. I called him and left a message but he didn't return it. I called the main number which took hours to call me back just to say that they had to call me back again. When they called back the next day, they said that Ben had informed me that I would need new battery terminals...WHAT?? He NEVER mentioned anything about the battery terminals and his report has nothing to say about the battery. He either lied to the office or neglected to tell me or put it on the report. So then they asked me if I wanted to set up an appointment to get the terminals installed....NO!! I'm not booking another appointment after that!! Are they crazy??? I'll get someone else to do the terminals and I will NEVER use YourMechanic again.

All about Oxygen Sensor Replacement

With each new model year, manufacturers are adding more oxygen sensors to better manage engine operation. Some high performance engines have an oxygen sensor for each cylinder as well as one for the rear of each catalytic convertor. The sensors are located either underneath the hood or underneath the car. The oxygen sensors are connected (screwed) to the exhaust pipe, either in front or back of the catalytic converter. The front (upstream) sensors measure the amount of oxygen in the exhaust system. The purpose of the front oxygen sensor(s) is to measure how rich or lean the gases are as the gases exit the combustion chamber. Depending upon whether the exhaust gas is lean (high in oxygen content) or rich (low in oxygen content), the amount of fuel entering the engine is adjusted by the engine management computer to try and maintain an ideal mixture that produces the lowest emissions output from the catalytic convertor. Rear (downstream) sensors are located behind the catalytic converter. The purpose of the rear oxygen sensor(s) is to monitor the oxygen content of the exhaust gases leaving the catalytic convertor. If one or more of the oxygen sensors are faulty, your car may not pass the emissions test. If you drive your car with a faulty oxygen sensor, you may get poor gas mileage and it can damage the catalytic converter.
