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.

First it was he didn't have enough employees, then the wrong transmission. I went down once a week to check on the progress, both seats were reclined back and I saw bags from take out restaurants left sitting in my car. They couldn't find the time to fix my car but they found the time to use my car as a break station. NOT COOL!!

The California registration is due so we were going to get this smogged in El Centro. We have called this guy three times and he is just so flakey. The first time we called we asked if he was open on Sunday. He was like 'No, but if you call me I will come down and open for you". So we called on Saturday to see if he was still up for it. Nope, come in on Monday dude. He also asked us what year the motorhome was at that time and we told him it was an 81. So, we forgot the paperwork but were going to see if they could still smog for us. we called again and hes like "dude I cant work on anything that old". WTF man.... you knew yesterday how old it was. We are grateful that we didnt drive all the way there to get it done and THEN have him flake out on anything from the hours of operation to what he will and wont work on. We are going to take it elsewhere. The other people we called seemed really nice and told us everything we needed in the first call.
