Subject:      I think I TRULY fixed my surging problem
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Well I think I finally figured out/fixed my problem (surging on my '84's
1.9).  I determined that there were no vacuum leaks.  And after all of
the components that I had changed (vac hoses, o2 sensor, plugs, heads,
etc.), I thought I might have fixed a problem that had been lurking
before and perhaps been bandaged over.  I had gotten my idle to stop
surging (or at least not AS bad), by turning my idle speed screw in a
couple of turns (I was confused though becuase my idle speed never
really changed... at least until I turned it a few more turns and
realized that it had been turned out so far that it wasn't even
registering).  Then I screwed up my courage to attempt to adjust my CO
screw, since despite working out my idle and surging my O2 sensor was
still stuck around .9.  I went to turn it in a little and it wouldn't
move...darn thing was fully seated.  As I turned it out, I slowly
watched my O2 readings get closer and closer to spec until it got to
around .5 at 3.5 turns from seated.  Now it's smooth and surge free
(yeah!).  Thanks for all the advice guys.
