Lucas

I cannot even BEGIN to tell you how happy we are with Lucas. He quickly identified the problem, explained the basics of what was going on, and THEN he mentioned that it may still be covered under the manufacturer's warranty. He gave me step by step instructions who to call and what to ask for. As if that wasn't enough, he sat with me and my infant son in my car while I called the dealership to make sure I was asking all the right questions. In the end, he was RIGHT! We got a $400+ repair for free from the dealer!!!! I realize Lucas could have easily just done the repair, made some quick cash and not mentioned the warranty, but what a good and honest guy he is! We have some work we need done on my husband's car and we're totally sold on Lucas and Your Mechanic.

Trung Do was very professional. He was very good with communicating before appt with phone calls. Called when he arrived. Finished job very fast. I will use the service and Trung Do again. It is great for someone who is disabled and more comfortable sitting at home and in a shop waiting room. I wish I had known about this service sooner.

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.
