there is a sensor right above it on the back side of the engine, it is almost more convienient to just take the intake manifold off to do it. dude is right it is a PITA. I think it is some kind of intake air sensor, and if you damage that connection, the car makes all kinds of funny noises when you step on the gas. That sensor if not in place makes the whole car lope whenthe accelerator is depressed.
I like work, it fills up the days between weekends...
