So I drove my car to services **** and I had a misfire on cylinder 4 they charged me for disagnostic and for disassemble and for further troubleshooting which they provided a rental while it was at the shop. After like 3-4 weeks they said metal teeth from the vacuum pump feel in the cylinder which was false,and they recommended I get a new engine assembly which was going to run me ******. So after that I bought an engine from junk yard to do it myself and the metal shaving were right under the valve cover and I fixed the car. They charged for what they did and gave me false information and I spent *************************************************************************************** wrong information and paid them almost **** for test plus had to deal with the stress of being with only one car for the family and my wife also works so it was stressful and I would like to get a refund and also money for the junkyard engine I bought because of there bad/false diagnostic information. I also had to pay to get my car towed back to my house because it was disassembled and not running even though I drove it to their shop. I feel like there tech/mechanic doesnt know about maintenance. Would like to get like 2500-3000 refund since I spend money for nothing this visit to there shop was basically robbery.
