Don't Just Take Anyone's Word For It

We have worked hard to be one of the best service facilities where you can bring you car. We hold ourselves to high quality service and repairs. One of the areas we’ve held true to is, we do not work off of other people’s diagnoses, and this includes the Dealership’s. Everyone makes mistakes/misdiagnoses, including us, we are human. One thing I get a kick from is a tow truck driver’s diagnosis. Have you ever had the unfortunate luck of having your car break down on the road, requiring the service of a tow truck and had them tell you what wrong with car as they are loading it onto their truck? Really? If these gentlemen really knew what was wrong with your car, why are they tow truck drivers? We spend a lot of time and money to keep up with the technology that goes into these cars. Our technicians go to classes yearly to keep up with the changes these car manufacturers come out with every year. We focus on only the cars we work on. We purchase diagnostic equipment from the factories and the people who build the vehicles, not a generalized version of diagnostic equipment, to give you the best possible service we can.

I get a lot of phone calls where someone has gone to an auto parts store that will give you a free diagnostic reading of your ‘CHECK ENGINE’ or ‘SERVICE ENGINE SOON’ warning lights. These generic OBD II readers are just that, general reading. For example; one of the most common complaints I see and hear is: you go in with a ‘CHECK ENGINE’ light and the store reads the code. The code comes up as an oxygen sensor fault or failure. You have the oxygen sensor replaced, but the light remains on and the fault returns. How can that be? You were told that was the problem, or was that really the problem? The fault is more than likely the result, not the cause. Oxygen sensors on the cars we work on have come a long way and do not fail that often. Usually what we see is this: your ‘CHECK ENGINE’ light comes on, we check for the faults, and the fault comes up with an oxygen sensor fault or failure. After running a diagnostic check of the system, we find that the fault is a ‘lean running condition’ or too much air in the air to fuel mixture and the oxygen sensor cannot adjust the ratio because it is outside of its parameters. Further investigation will probably find a vacuum leak or old and cracked intake induction boot allowing too much air into the engine, and THAT is the problem, not the oxygen sensor. This is why, no matter what kind of car you drive, you should always find an independent shop that specializes in your car that you like and trust. Let them look into you problem, this is what they do, this is their job.
