it's not egr if its doing it cold. anyway
test the egr system, rather than clean.
ignition. plugs, wires, coil pack, ignition module.
my suggestion is test and isolate the problem first, before doing
anything.
i have had the coil pack problem too, and as stated above, this sounds similar to my symptoms, too. it's pretty easy,and cheap, to test first.
the old remove the spark plug wire trick to see if all cylinders decrease in rpm relatively the same. and/or use an inductive timing light on each wire. and/or use a cheapo (or expensive-o if you're so inclined) short tester along each wire. and finally, go out in the dead of night, pop the hood and look and see if you see any sparks aflyin. i did. and it turned out to be one of the three coils (which provide the spark for two cylinders, but it was just one cylinder that dumped in my case)
i ended up replacing the whole module with all three coils, but you can buy the coils individually and replace just the one if you wish.
