Brikk was great. We asked him to change out the alternator on my sons Saab based on a noise he was hearing and also from a garage he took it to. They said the noise was the alternator and it was about to go. He did not get it done at that garage because they want over $800. Brikk listened for the noise but was not convinced it was the alternator. He said it was putting out what it was supposed to. Unfortunately on that day we were not able to produce the noise so Brikk said to contact him when its making the noise again because he would like to be sure. I don't think the noise has come back so far. Its my sons car so I have never heard it. So we are kinda waiting to see what happens but Brikk was great, informative. I like this service very much so far in the few time we have used it.

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.
