I posted a reply to one of the EGR messages in one of the forums last night, and it never showed up.
Anyway, I am experiencing some of the herky jerky under light load and with the mixed results of cleaning the egr valve, I think I'll just replace mine. I looked at the Majestic site, and wasn't able to find the EGR valve. I couldn't find it in the exhaust, or cyl head, unless they call it something else.
Thanks,
Robert
