Not Passing Emissions

[MobyDick]

For some reason the monitors in the computer in my 98 Mark will not reset so it can pass emissions. My mechanic has tried everything he knows how to do. I would appreciate any ideas from someone more knowledgeable about this issue.

Do you have a TUNE in the computer?

Well, I was just driving it 15 miles in hopes it would reset, but I did not do what this article lays out. I will try this. Thanks.
