Well, no. But along with all that other stuff in the other e-mail;
On 12-5-96 @168k we replaced: the throttle body boot, exaust from heads to
cat [factory stock VW (read, $$$ ouch!!!)] , throttle switch and O2. There
was a second O2 at 214k. The ECU is also "new" used from a list member.
The muffler could stand to be replaced as well though because the inlet
pipe rattles around and make a racket. But it has "hunted" for a while and
I was able to adjust the idle screw in a bit and make it disappear. Now I
can crank the screw all the way in and nothing much happens, whereas it use
to almost shut down. So my next (argh) task is to find the vaccum leak
wouldn't you say? I think I'm going to take the tack of replacing all other
vaccum hoses. Sound reasonable?
This thing is going to be new pretty soon.

Thanks, again!
