Wish I could give 6 stars - not just 5. Robert's attention to detail was extraordinary. After pre-evaluating my vehicle just to ensure that we were dealing with the right set of issues, he came in and spent the entire next day bringing my 'baby back to life. Not only did he revive her, and get her humming again - he broke a number of his own tools in the process - but that just motivated him even further to persist until she was back in top condition. If you want someone determined to go the extra mile, Robert's the name. I think I may have found "my guy" - as they say.

Honorio arrived promptly and advised services that wee more appropriate for the car at the time versus what i had ordered. It meant rescheduling, but we will end up with a better solution as a result - and not necessarily more expensive than where we started. I appreciate the honesty and knowledge Honorio provided.

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.
