Meanwhile 13 years later . . . The above mentioned website appears to not have a tech section anymore and I didn't find a mention on their FAQ page. In case anyone else was curious about what they said I was able to find it here . . ...

The Solution to my Issue I would like to thank everyone who took the time to offer suggestions and advice. With the limited information I gave, all of your responses were valid and I appreciate your input. Special mention to @trippled and @Tim_MN. I checked many of the things suggested by...

At this point I'm not ruling anything out. Maybe I don't know what a misfire is but the pattern is it only happens in either 3rd or 4th when it is about to shift down. To me a misfire is when one or more cylinders stop producing power. The jolt I'm feeling is more like all cylinders decided...

Yes Dex/Merc. Loks great no smell. Will checkout the manual. Thanks.
