On time, courteous, and helpful. A few days later, my car became sluggish and noisier than usual and my check engine light came on. I spent a few hours and bought tools to diagnose. I discovered that a hose had a come loose and was disconnected. I believe that the hose bolt was loosened when Grzegorzs was checking my air filter.

Theo was ontime and extremely courteous. He diagnosed my vintage Mercedes' problem and returned a week later. The replacement part they sent him was incorrect, so he reassembled my dashboard and waited for the correct replacement. When it arrived, he not only installed it, but followed me to a service station and then test drove the vehicle to check for other problems. I will ABSOLUTELY use Your Mechanic.com in the future to avail myself of a great mobile service. Thank you.

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.
