Walt is a hard working honest man. It may take him a little bit to get to it if you do not make a apointment. It is well worth it though. I had my van into him just this week. When it first came in he said it may be a catalatic converter but let him do some checking first. Some guys may have just changed it taken the money and hoped that it fixed the problem. In stead he took the time to check a couple of other things first. He found that my air filter was dirty and that the fuel filter was so plugged up that he could not even blow through it. It was great to learn that rather that a $900 to $1200 fix it was only about $150. It is well worth the wait for an honest job now days.
