My fuel filter had to be replaced. I tried for two hours myself and could not get it off. Called Porters and they said come on in an hour and they would take care of me. They replaced it at a very reasonable price. Had a very rough running motor. They diagnosed the problem. Removed 3 catalytic converters, two of which were completely clogged. Replaced 3 spark plugs,fuel injector, and noticed both of my sway bar assemblies we're missing both top and bottom bushings. Also car was rolling backward while in park. Found the problem and replaced both bushings and no more rolling back. A along the way they showed me the defective parts They are honest , do excellent work at a very reasonable price. Highly recommend Porter's. An honest ,good mechanic is very hard to find..I found mine!!
