Glen -

The seat in the stabilizer is almost certainly worn to where it
won't seal air.  Thus, it allows varying amounts of air to leak
past, making your idle high and all over the place.

I had this exact same problem.

Try plugging the stabilizer solid with something and see if the problem
goes away.  DON'T use RTV silicon rubber, because that will poison the
O2 sensor - then it won't work either ... again, I screwed up and did this
myself.

I recently bought an aftermarket stabilizer, paid $139 for it ... and
when it arrived, it's marked "Made in Russia"!  Seems to work OK
all the same.

This was mail ordered from:

    Recycled Bugs
    2300 N. Opdyke Rd.
    Auburn Hills, Mi 48326
    (810) 373-2315

Wish ya luck!

I also replaced the O2 sensor with one of those fits-all models,
and only paid about $70 for it  :-)
