Default New ICM Now??
When I rev up my engine even tho I have regapped 1.5 year old plugs and brand new wires I get a chugging noise....Seems to idle fine but when acceling or reving in park I get a chug... Should I get a junked ICM and see what happens? I tried switching the coilds around and that didnt work...

My opinion is that isn't your ICM.....Maybe fuel related? Like a plugged fuel filter or a pump goin out maybe?

Try cleaning your tb and MAF and IAC? Sounds like maybe it could use a good scrubbing.
