Guys, Need help with the wife's excursion--2004 w/6.0. Plugged in the Mac Taskmaster and got these codes with KOER. Didn't do any of the other test. Truck has gotten very sluggish. Believe code has something to do with ICP. Can someone give test procedures,etc. on what to do and what to look for. Thanks in advance because if momma ain't happy, ain't nobody happy.
