Very poor communication, odd that this seems to be a common complaint for this business. I took my vehicle in for poor acceleration troubleshooting. They called and said they thought that it was the coil. so in addition to the troubleshooting fee,.....they charged me for 0.7 hours of labor to install an ignition coil, that my 13 year old son can do in 5 minutes. I had told them that I wanted to buy and install the part myself as I needed a warranty from autozone, as I had just replaced the coil and I didn't want to be in the same boat later. I'm sure that this upset them as they wanted to get a few extra bucks for installing the part. However I did not authorize them to do this work, they did not inform me that I would be charged .7 hours to FINISH TROUBLESHOOTING and make sure that the problem was indeed the coil. The owner also refused to give me a military discount, even after I had to inform him that his website stated that they do have one.
