If the motor is getting EGR when it is not desired, it can lean the mixture enough to induce a misfire (and rough idle) and effect the HC emissions
My truck does the rough idle thing, I am thinkin about tryin this, seeing how it works. GOt it from pirate, that thread was really interesting, gave some good suggestions

For those wishing to bypass their 'functional' EGR valve, all you need to do is unhook one end of the vaccum line that actuates the diaphram, place a bee-bee or ball bearing in the vaccum line and then hook the vaccum line back up.
This method works great for those of us in states that have 'visual' emissions inspections. For all intents and purposes the EGR appears as if it is still present and functional.
And if the situation should arise where you need to reinstate the EGR to its former 'glory' all you need to do is trim back the vaccum line to free the ball bearing plug and hook the vaccum line back up.
