Re: etest failure?
I failed my Maryland test last month. Ran it about 100 miles at highway speeds, as suggested by my SUBARU techs, and got with 187 points of passing. I brought it to Heritage Subaru. They thought that since i did not drive it that much it had a lot of carbon build-up. They put some cleaner in it that had to sit overnight to dissolve/break up the carbon. It apparently worked because when I brought it back for its test I had the best readings since I replaced the entire exhaust sustem 5 years ago. I don't know what they used but it sure worked.
