[DML] Auto-enrichment??




Ok, here's the story.

I wanted to put my A/C belt on.  Through this process
once I was done, I was reconnecting the three lines
that go from the "coal canister" in the left of the
fiberglass body to their individual placements.  Got
two out of three hooked up - last one went under the
intake.  When I connected this one, the hose on the
right was hanging in my hand.  I realized the only way
to reconnect it under the intake was to pull the
"elbows" off the front of the intake.  So I did this
and reconnected the last line.  Put everything back
together the way I found it to a "t".  

Started the car, runs fine when warming up from
100-160 - oscillates a little for 1-2 mins as normal,
then idles perfectly (I'm one of those "Non-Lambda
system" owners - O2 sensor is unhooked for a "smooth"
idle right at 800 rpms or so).  Now, my problem is
from 160 (first unmarked line) to 220 - the car begins
to RE-oscillate - as if it's running too rich while
warm.  It will do this until the cooling fans come on,
then of course it'll stop oscillating due to a load
being put on the engine.  Once the fans turn off, the
engine will slowly begin to oscillate again gaining
with the oscillations becoming stronger until the fans
come on again - over and over and over.  

The idle once held perfectly steady in all gears, now
it does this.  In "D", it does still hold steady, but
in "P" it does all I described.  I don't know a single
thing I could have broken.  The only lines I remotely
tampered with are the 3 black ones that go over the
A/C Compressor.

One thing I have noted is if I disconnect the bottom
black line off the cold start valve, the engine will
idle perfectly in all gears, so somehow it has
auto-enriched itself.  I don't know how, and I don't
know what to check to lean it back down other than of
course the mixture screw.  Any ideas would be
welcomed.  Thank you.

Jeremiah
