Default reasons for misfires, plugs are brandnew IK22's and misfires occured on stocks aswell..

after my new turbos were installed I have been getting a weird idle. However the tach doesn't move, it only sounds as if the car is reving sporadically. I keep getting CEL's because of the misfires and then they go away if I dont clear them.

Default coilpack? output stage (aka ignition amplifier)?

Which cylinder(s) are misfiring?

If your getting a CEL, then it's probably a coil pack heading south.

Default The old plugs might have been ready for a swap...

leading to the misfire codes. Improperly gapped Denso's will lead to misfires as well. PaJohn went through this...do a search, and see where he finally gapped his plugs. If your plugs are gapped at that setting, double check them...don't take it for granted that they are correct.

Default I believe that would rule out the ignition amplifier, had this problem on a 1.8t, it was always the

same cylinder. You could try moving the coilpacks around to try and isolate the problem. Since you thinks it's multiple cylinders, seem odd that you would have more than one coilpack fail at once.
