I bought a used Subaru and after owing it less than a month it just wouldn't start. After some bad luck with a previous mechanic I was worried I had bought a lemon. Then I called Your Mechanic and made my appointment with Russell. Russell is very knowledgeable, and knew all the little quarks about Subarus to check. He explained the steps as he went through them, told me exactly what he was looking for. Russell found the problem, a bad battery wire, and replaced it. It was such a relief when my engine turned over. Russell noticed that the engine sounded a little funny and he took the time to tighten some bolts, now my engine sounds better than ever. He also checked the oil and pointed out that it had been over filled. I will definitely be booking Russell again. His attention to detail and professionalism is so far above any other mechanic I've met.

My appointment was late in the day so I was not surprised that the mechanic was a little behind schedule but was pleased to have gotten a call to say so. The job was done in good time and clean. Theodore's experience showed in our conversations about the work, other potential jobs, and whether they were worth it to me as I decide whether to keep the car. Very patient, careful explanations that expanded my own knowledge base. Definitely my first call for next time. Thanks Theodore, and a great price!

Tyler was awesome to say the least. He was prompt and good about communicating with me throughout the entire process of working with him. He fixed a number of issues with my car and I have the quotes/invoices to prove that I saved over 50% by using YourMechanic over said autoshop. I will definitely look to book work with YourMechanic, and specifically Tyler, for any car care needs in the future!

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.
