I own a 91 Dodge van which was due for an emission test. My "shade tree" mechanic had retired so I had to find someone new to ready my vehicle for the test. In the past I had used a big name service, one with all the diagnostic equipment, and $800 in, I still couldn't pass the inspection. I tried Ken' s on the recommendation of a friend. Not only did they tune my van, they drove it to the inspection place and had the test done for me. And the price was very reasonable. (Yes, their diagnostic test told me that I needed more expensive work down the road. But those issues were not forced down my throat!)
