Thanks for the feedback. I'm getting ready to do a 150 mile road trip for business today, and I'll try disconnecting the EGR to see if it helps. If that's it, shouldn't be a problem building and installing the restrictor plate (fist time I've regarded restrictor plates as a good thing!).

We don't have emmissions testing in San Antonio yet, so I'm thinking about just plugging the hose, and pulling the bulb. If we get testing here, (they're talking about it) it'd be simple to hook up the hose long enough to "pass the test". This would eliminate ANY exhaust gas in the fuel mixture. Whaddaya think?

Thanks...
