Thanks 360ci... Used to live in Waterloo...
After doing some research, I found a recall 04N02 (fuel module replacement), and had the work done by a Mercury dealership. After they finished, they reported a CEL light (code P0420), which was not on before their work. Checked out with another shop, applied a TSB to reprogram the PCM. Still no help, so I bit the bullet for a new Bank 1 catalytic converter. Dealer wanted $2100 to replace, but my had it done at the other shop for $800 (using Mercury parts).... nice markup/robbery by Mercury dealer!! Jury still out, but CEL not on, and no hesitation. Here's hoping for the best......
