15 June 2015 Review: YourMechanic.com Recently, I had the opportunity to check out a service that I had, for quite awhile, wondered about and would it fit with the ever-changing consumer worldview. Okay, at least, here in the United States. YourMechanic.com offers to come to you and service your vehicle's needs. While you continue your work day; they continue theirs. When all is done, that's exactly that. They're done with their day, you're done with your day and the day-off your car unexpectedly took is also done. Now, you're back on the road or at least able to head out if there's someplace you have to be. Although this may not be a new service; it is for me. I'm glad I found it, used it and now I can recommend it. The mechanic I met, Peter, came with 35 years of experience, licensed, prepared and engaged. I haven't found that at decades old, established companies anywhere, ever. Perhaps, that old model, along with its particular brand of hassles and drawbacks is becoming obsolete. One thing for sure, it won't be missed by me. In as much as the auto/mechanic industry is not my primary area of expertise, allow the following illustration which draws on my personal background to drive home the point: If YourMechanic.com were to announce an Initial Public Offering (IPO) tomorrow, you bet you'd find me among those first in line positioned to grab up as many shares as possible for a long term "hold." Regards, David Duke, Phoenix, Arizona *Note: Please strike this note from the official review as it is intended for inter-office use only. Please feel free to correct any glaring typos I may have overlooked. I am submitting this with a deadline in mind.

My appointment was scheduled for 10:00 a.m. Kyle called to say he would be about 25 minutes late. He arrived when he said he would. He seemed knowledgeable and was polite and friendly. He quickly came to his conclusion that my old Buick was done and I should look to buy another vehicle. A little too quickly for my liking, but he was not trying to sell me parts or services I did not need. He gave me good advice on how to financially maximize what's left of my old car. My only criticism and it's a small one, is that he did not seem interested in hearing my opinions or comments about what I had done to or replaced on the car. He seemed confident that my vehicle was beyond repair and moving on was my best option. I would use YourMechanic Services Inc. again.

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.
