Tune solve misfires?
I'm not trying to argue with you nor am I using exclaimation points to end every sentance. I agree, normally a P0300 code is not the result of an EGR problem. Here's the thing, its an 06 and it probably doesnt have 2 unrelated problems. It probably has 1 that is causing the other. P0300 could be a ton of things and he already eliminated a few of the most likely causes (plugs and wires). A vacuum leak is still a strong possiblity. Do a leak test it may solve both of your problems if you have one.
EGR's valves can fail 2 ways. Stuck open or stuck closed.
An EGR valve that has failed, refuses to open (or the EGR passageway i the manifold is clogged) will allow elevated NOX emissions and may also cause a detonation (spark knock) problem.

nox is the last gas you consider for any for of diag. with a concern like this. why is that even brought into this (its the 5th gas in 5 gas) use to be four but they made em put it in there.
and then you go ahead and edit your last post to match up with the two fellows below who made very good and contributing points
im done with this one... hope you get your car fixed dude!

In my next post I suggested that he look for vaccuum leaks because I know that is a leading cause of P0300 as well. I had a P0300 problem for months.. believe me I've done my share of troubleshooting this issue (plugs, wires, leak test, compression test, etc). In spite of all your attacks of me the only suggestion you offered was to check the gap on his plugs. Good suggestion except he already did that. His vaccuum leak is probably the cause of his P0300 as well has his stuck closed EGR valve (no vacuum to operate it).
I'll probably get in trouble for getting off topic but I'm trying to figure out why you have an attitude with me. I just tried to help the guy out by posting the OBDII codes for the guy, along with troubleshooting steps, and advising that getting his evo tuned would probably not fix his issue.

The misfire is noticeable at idle only. I dont feel it while driving. The car goes up to redline smoothly. I tried to unplug the battery and back on. The cel went a way but a while later, it'll turn back on. I just check the vacuum lines and i did find the egr line disconnected. I put it back on and zip tied it. Well I tried. I only had big zip ties and it seem to be big. I"ll go back to it later with a smaller one.
