I have a 1997 Chevy tahoe with about 135,000 miles. Usually when traveling up any grade & when excelling the SERVICE SOON light comes on. It will bog down a little. The light will stay on for the next 4 - 8 starts. One mechanic got into the computer scan code and found code P0300. Found 5 of 8 cylinders misfiring, # 4 however had misfired a total of 4,877. The mountain mechanic wher I live did not seem to know what was causing it & "Would have to read up on it" as it could be one of many things.

I went to the Bay Area & my son highly recommended M & M Auto saying they were good & fair. Well they called me & told me what the problem was after about 1 hour & told me what I needed. He said that would fix it. This had been going on for many years with no answer prior to going to M & M Auto. Well what a difference since M & M Auto worked on & fixed the problem. It will zoom/excel up any hill with no loss of power or bogging down. I will work my visits to the bay Area around my vehicle needs as available as I am highly impressed with M & M Auto. I might add their work bays are also kept clean. It does not look like Sanfor & Son wrecking yard if you know what I mean.

Thank You Richard, Susan, & Bella!!!! I will be back again.
