Robert showed up for the 4 p.m. appointment today to look at my 2004 Volvo XC90. He was courteous, and tried his best to evaluate the problem. A foreign vehicle is very hard to disagnose, and I believe that after my experience with both Robert and another car mechanic at a different shop (who looked at the Volvo as well and did not charge us for diagnoses, since he could not figure out the problem) that it takes a Volvo specialist to evalute and to accurately diagnize the problem with this vehicle. Robert made a couple of guesses, however, he did not know exactly what the problem was. He told me that the car needed to be placed on a jack high in the air to completely diagnose the problem. He said I needed to take the car to a Kaufman tire to get a complete diagnoses while the car was on a jack high up in the air. He told me it would take 2 people to diagnose the problem. Robert tried his best, however your company did not have the resouses & equipment to accurately diagnose the problem (jack lift) according to Robert. Also Robert said it would take two people to diagnose the problem as well. I am going to take the Volvo to someone who works with Volvo's to accuratley diagnose the problem. I am confident that you will refund the $70 charge that you charged my credit card since Robert told me he was not able to accuretly diagnose the problem. Thank you. Rich Whitmer 404-379-1625

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.
