Ben

Could not have asked for a better mechanic. Ben arrived 15 minutes before appt. (what a wonderful surprise), got to work on my car, was finished timely, cleaned up the door. He was polite, cheerful and personable. It was such an unusual experience to have a mechanic who fixed your car and didn't try to "sell" you more that was needed. Usually my husband has to first meet the mechanic to ask for an estimate because we found out that it's always higher when I ask for it! I will recommend Ben to my friends. By the way, Ben was recommend to me by a friend of the family Cedric Senter. (he should get the $20 you offer for recommending Yourmechanic)

I was admittedly skeptical - surely the sequel can't be as good as the first one! - but Jeffrey was a joy to have working on my car! He initially inspected my car to correctly determine the problem, and when the quote turned out to be not only reasonable but extremely competitive I didn't waste any time having him come back and replace the starter in my car. With the mechanic being such a nice guy, and the price beating the local, tradition auto repair shop, having him come to me simply sealed the deal! This respectful, knowledgable fellow is now my mechanic, and he should be Your Mechanic, too!

Rodney went above and beyond working on our 1993 Buick LeSabre. The auto had a start run briefly then stop and would not restart. Rodney replaced the suspected (code 18) part crankshaft positioning sensor, the crank pulley. Auto does not even start now. There could be other potential issues as is the case with the early mid 90's GM autos. There could be other suspected other parts and issues here. Though I do believe that your mechanic should send someone to further investigate this problem at no charge, after all the car did start now it does not!

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.
