When a company performs a tune up consisting of replacing spark plugs, their wires, and a fuel filter, it's amazing to see my vehicle performing as poorly as it is. The so called mechanic/owner rules out one possibility by performing certain tests right in front of a customer and turns around the next day and says it IS the problem makes it hard to believe they know what they are doing. Especially since the solution they now offer is the most expensive work they can do, but again they don't even advertise that they do this kind of in depth work. Are they even certified to do this? Where would I be if I let them perform this work and it isn't done correctly? I fear something may have been tampered with when I left my vehicle alone in their care. No documents were ever signed by myself or even shown until they were asking for their payment. I will be doing research to see if filing a claim with my auto insurance under the clause of vandalism will help me be able to make any potentially expensive repairs to my vehicle because of their negligence.
