i havent had that problem and dont really know how a clogged egr can make a misfire. i can under stand if its stuck open itll cause it. how old are your plugs? what are they gapped at? do you have cams and or a tune?

If you haven't fixed the problem, check your EGR and make sure that the vacuum lines that run to it are actually hooked up.
I had crazy misfire issues and was informed to check the vac lines on the EGR valve (thanks again GST). Problem solved... use a zip tie and a bit of hair spray to keep the line from popping off.

Remove your EGR valve, install an EGR block-off plate, and disable the EGR emissions checks in your ECU  Cheap, easy, simple!

do you maybe have aftermarket exhaust ? not running a simulator? this could trigger the o2 code.if so return the o2 sensor and buy the 3 dollar spark plug non foulers
