Jorge Cisneros is a sincere and competent man. Before taking on a job, he took the time to listen…read moreto my situation and to decide whether he help or not. In my experience, his attentiveness and honesty were well displayed by the fact that he took on a job and did it on time for an extremely fair price. Cleaning out an exhaust gas recirculation system is something a lot of garages simply don't want to do, and will become dishonest when facing a request to do so. I have experienced this with some businesses for whom I have left appropriate reviews detailing as much. One business even immediately tried to convince me that an engine replacement was obviously necessary. 2 days ago, a 304 code was showing that my fourth cylinder was misfiring for some reason. Mr cisneros took the time to comply with my request to examine my EGR system and confirmed that the first three intake manifold ports were blocked significantly, routing an overflow of air to the fourth cylinder and causing that misfire. A combination of free code readings and YouTube videos and a replacement of spark plugs not solving the issue made this EGR clean out a very likely solution to my problem. Indeed, I have gone from about 35 miles per gallon and a knocking engine at low accelerating RPMs yesterday to over 50 miles per gallon and an engine that purrs ever so gently if audible at all today. I was pretty sure of the problem and the solution, but Mr cisneros is the person who made it possible. I can't recommend his services enough, and I hope that other people have a chance to enjoy the same experience that I did! My dented Prius has 200,000 miles on the odometer, but thanks to Mr Cisneros, it's still a young car.

Although MTZ could not assist her directly they put me in touch with a company that found her and was able to tow her stateside. MTZ was amazingly concerned and helpful. Not that anyone ever wants to find a tow company but if you ever need one, I strongly recommend MTZ. I can only imagine the care they would have taken had we been paying customers!
