I was very impressed with Theodore. I took a chance on using this mobile mechanic site and was nervous at what to expect. He came on time, did a really good inspection and made recommendations what I needed. I booked him because my driver side window was making a funny noise and I thought I needed to change the motor. He spent a good amount of time looking into the issue and explaining to me as he went along. I will highly recommend and plan on using him again.

I have to say that I was a little apprehensive at first. Being a Mercedes driver, I've come to know that servicing these cars are anything but normal. So in asking I found that Peter approached this job different from the dealer. My mind was set to rest with a detailed explanation from Peter. He does excellent work with excellent cleanup as well. I was very happy with the outcome and also pleased that he was on time, early actually and very professional. I will be using him again I'm sure. Michael C

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.
