If EGR is creating a misfire at idle there is more than likely a leak at the EGR valve allowing EGR by when it should be closed. Sometimes a good cleaning can rejuvenate the valve. Always, high quality maintenance will eliminate the problem without resorting to tweaking something that doesn't need to be.
As a side note, EGR gained a bad rep in the late 60's early 70's when first installed and systems were sometimes valve incorrectly as per drivability, and instead manufacturers preferred to err towards emissions. Surging, very noticeable part-throttle issues, and substantial pinging were all factors that were part of new and improperly tuned cars that set many peoples minds forever against it. A modern, well set-up and functioning EGR is virtually not a problem at all. If you are seeing a problem that EGR seems to be involved with it's probably another part of the system that is causing it, not just the fact that the system is plumbed into the combustion chamber. The young people driving and working on cars today have it easy compared to the mess of hoses and lack of information of 20-30 years ago on carb'ed vehicles.
Again, EGR was specifically designed for cars that were idling alot in traffic. I've cleaned solenoids and it doesn't last long for some cars. I have a 03 crown vic with 35,000 miles and the egr solenoid has clogged up with the 2nd valve installed. WHy deal with it when you can remove it and not worry about the solenoid design flaws causing malfunctions. Plus, since my car is turbocharged I didn't go through a welding ordeal to plumb the line. Kids do not have it easier today than previously. If you think a carb'd v8 or such is harder to work on you need help.
