For the better part of a month, I’d been panicking over my 2002 BMW 330ci, which had basically lost all power, so it was just sitting in my garage. Towing it to a shop for diagnostic testing was an option, but then I’d be stuck in the event projected repair costs exceeded the car’s worth (or even half of its worth). Being stuck sucks, so I decided on exercising another option. After reading a bunch of reviews and doing some research on Your Mechanic and their team of mechanics, I decided on giving them a try. I am so glad that I did. What an outfit! Great concept, great execution ... The people in the office are wonderful at keeping you informed, answering questions, from beginning to end. Their online presence and transparency dismisses any weirdness customers may feel about the whole inviting strangers over thing, too. And Your Mechanic delivers, by connecting top-tier mechanics with people who need their help. That’s exactly what Your Mechanic did for me, by introducing me to Chris M. He came to my rescue. What a pleasant polite young gentleman, Chris is. And Boy oh boy!, does he know his stuff! With patient professional confidence and calm, Chris ably diagnosed my car’s problems, tested the hypothesis, and retested too. The problems weren’t easy to find or common whatsoever. Thanks to diligence and expertise, however, Chris M. identified the issues. It wasn’t piston rings or the catalytic converter, as I’d feared, but a faulty engine coil. Chris explained the issue, actually showed me what was going on in the engine compartment, provided me with a detailed quote that I knew was fair and reasonable (talk about a mind Blow!), and then he even offered to come back and do the work, if I wanted. Heck Yes! Chris came back the very same day to render the fixes, all from inside of my garage. No tow trucks, no queue of customers waiting, no worries about surprisingly huge repair bills, and no concern about strangers coming over, or anxiety about non-OEM parts. I have a brand new engine coil, new spark plugs, a clean gas line, clean oil – and a renewed confidence in my automobile’s reliability. Presto! My car runs like a charm. Chris M. earned my confidence, my trust, and my respect – and that’s an amazing feat. Having a qualified, knowledgeable professional come to my home, diagnose my car’s troubles, and even render repairs on site, using manufacturer-recommended parts, sounds like a luxury I couldn’t afford. Turns out I was wrong. No doubt, from here on out, I will be recommending Chris M. and Your Mechanic to anyone and everyone.

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.
