its a bugger to get at, but you can do it with out removing much.
I just had to remove the air hose in which the moose fix is used (dunno the technical term), it runs from the UIM to the airbox.
a few quick turns and poof, out. I did loose a fair bit of coolant, so make sure you have something to catch it. or do it at night so noone sees you dumping Coolant into their sewers.
however, this did not fix my problem. I still have the CEL and my car is now hesitating at speeds below 3000 RPM.
at a loss as to what else this could be.
