Tien

Tien was great, but the app/business made two errors. A. You switched mechanics on me at 9pm the night before. Tien was unaware of this switch and couldn't make it to my house in time when he found out the next morning. I understand you expect your mechanics to be responsive, but that's unrealistic...consequently the customer paid for it. B. A customer support rep reached out, with what I believe is an automated email, asking why I signed up but did not book an appointment. I had booked an appointment; this showed disorganization and hurt brand equity. All-in-all if Tien hadn't been awesome, quick, courteous my experience would have been very different. Positives: Very convenient service. I feel it should be cheaper with the reduced overhead of a mechanic shop, but with discount was very fair. Effective and quick, no hassle. Negatives: Y'all need a redesign on web. Haven't seen app, but web is kinda 2005-ish. Thanks for the oil change and I'll recommend y'all (and Tien) to some folks. Live long and prosper.

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.
