Emmette

Emmette was fantastic! He arrived early. He changed my one of my ignition coils and all spark plugs. When doing so, he showed me an oil leak seeping into the plugs which he explained caused the short. A different repair shop I went to two days prior advised e to change all coils and plugs at a price of $1,100, They never once noticed the leaking oil under the failed coil (and all others). When my car sputtered a bit on initial start up, Emmette insisted I take it for a ride while he waited for my return. He did so to ensure that the repair worked and I was satisfied. Emmette also inspected my entire car on his own accord. He sprayed a squeaky door, adjusted my tire pressure which was excessive (55 lbs of pressure instead of 32 in all 4 tires. This excess was done by a dedicated "tire" shop when they put my new tires on...What the heck!). He also fixed a bent gas cap (which is likely the cause of 2 EVAP leak codes). He did so at no charge, whereas the other shops wanted to replace major EVAP parts at yet another $1, 500. So far, no EVAP code has returned. I was a bit apprehensive having an unkown mechanic outside of a physical shop do the work on my BMW Z3. However after my exceptional experience with Emmette, I'm going to hire him to replace an expansion hose and to further diagnose and fix the oil leak he found.

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.
