I wish I could give Joshua a better overall rating. The process and experience was exceptional and I would have recommended him to anyone. However the $700 I paid to repair the car didn't fix the problem. I understood and asked that Joshua think more and converse with others as to what it might be for further action. I only did not receive a followup call from him but he hasn't returned my calls all week. I'm in a business where we can do a project 98% complete, but the client always remembers the last 2%. The great experience I had and the overall professionalism I was receiving has been soured by the lack of follow-up.

Resolved 4 out of 5 error codes. I was looking at thousands of dollars of repairs after speaking with 4 mechanics. He took care of 4 issues for the price of $100. I'll work with him again to resolve the final issue later.

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.
