I was a little reluctant to tackle this job being (a young) 82! But, the car stalled at idle and I was 10 miles from my service dealer, so I decided to tackle it. Also, hearing that it would cost anywhere from $400-$600 gave me the incentive. Here's a summary of my experience:
First the hose clamp on the back hose was put on backwards and the screw slots were not accessible with a screwdriver, so with the help of my wife's smaller hands, we used a socket to loosen the clamp enough to turn it so that we could use the screwdriver.
Secondly, we were unable to disconnect the black electrical cable, so we proceeded with it connected.
We were very careful removing the two screws to the black coil from the IACV so as not to lose the small wavy washer. As it turns out, that washer actually rests well inside so if care is taken, it will stay there.
We sprayed around the shaft of the IACV until it rotated freely and then reassembled (reversing the hose clamp, of course).
Started up immediately and idle is smoother than ever.
I must thank my neighbor in San Jose for this great post! :) :)
