not all that great at diagnosing problems but when you said that you replaced
the fuel pump to the Walbro, did you re-adjust the FPR? Maybe too much gas for a
cold engine to burn off until warm? Or what about a crack in the distributor
cap, letting moisture build up inside it from the previously warm motor (when
off) then when cold the moisture is preventing the spark from arcing? Had a
problem like that on my Harley with the coil-pack, wouldn't start until all
moisture evaporated (warm day or a hot motor). These are just guesses, again not
qualified as a problem solver. Good luck.<BR><BR>Ted Metzing<BR>93 TY

<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Unfortunately, I have
<EM>tried</EM> all those diagnostic trees-- even a couple of bushes for good
measure! This episode has been going on for nearly a month. As I
said, I'm running out of hardware to swap-out. The only things I haven't
diddled with is the <STRONG>EST Module</STRONG> in the Distributor and of
course the <STRONG>ECM/chip</STRONG>. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>The reason I haven't
fooled with those things is that the misbehavior complained of is SO
PREDICTABLE and only afflicts COLD-START-UP conditions, except when it's
really cold outside in which case I will get precisely ONE chug-a-lug spasm
about 5 minutes into the run-up to full operating temperature... just
after everything had been going just fine. That's the worst of it... as
far as I can tell without a scantool... seat-of-the-pants power and smoothness
is better than ever, otherwise. This is no "intermittent." This is
pure predictability! And my experience with bad chips and modules is
that they either fail outright or exhibit sporadic, random upsets... before
failing outright. That's not what's occurring. Even so, I might
drop in my spare EST (Holley Annihilator) just for laughs....</FONT></DIV>

size=4>:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Meanwhile, I NEED
HELP! With my laptop in pieces all over the bench, I can't run DIACOM
or DATALINK to give me clues about the usual suspects:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Clean-livin'
doesn't always pay off if my holidaze so far are any indication. I
spent Christmas Eve on a carlift taking apart my right-front axle-- again!--
after being assured by our local "Gear-Guru" (who fully rebuilt that
differential less than 6 months before I started hearing that
same CLUNKING on left turns again) that all I needed was a new cir-clip
(GM #14041989) to keep the axle from popping-out of the side-gear in the
differential. HAH! More bad advice and I ended up taking a cab
home.... More about that Horror Show in a later mailing.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Meanwhile, we got
our first technical freeze down here in what was becoming <EM>tropical</EM>
San Antone on Nov. 17th and our first hard-freeze, appropriately, on Dec.
7th, and somewhere in between those times ol' Syclone #773 began
<STRONG>throwing fits during start-up and for the first 5 or 6 minutes until
the water jacket hits and stays at 180°</STRONG> or so. I'm stumped
for the first time in a decade or more! Here's what
happens:</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Since the
<EM>new</EM> Walbro fuel-pump went in a few months ago, cranking times are
way down... engine catches pretty quick, but now it won't stay lit and
"choke" with the <EM>new</EM> IAC, which went in along with a <EM>new</EM>
TPS and remote-adjustable FPR about a month before the new Walbro.
Now, I have to feather the pedal once the ignition gets going and hold the
throttle open a bit while the IAC hunts for about a dozen cycles making the
tach swing about 1200 rpm back and forth until we hit the "sweet spot" and
the engine takes off smoothly and the IAC-hunting stops, at least for a
while. Now, it's safe to put her in gear and drive away as long as I
keep a little positive bias in the pedal for the next few minutes every time
I have to slow down to an idle or coast speed. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>THIS PROBLEM IS
WICKEDLY WORSE ON COLD DAYS, where ambient air is in the 40s or below,
which thankfully is rare. (Ain't this global-warming great!)
However, on a couple of occasions when I did have to drive in the 30s-- and
even <EM>after</EM> reaching full-warm-up temperature-- the engine starts
cutting out seriously as the SES light comes on! Now, we're talking
some MAJOR pumping of the pedal to keep things lit and if I can get on a
clear piece of road and cruise a spell at 35 mph or better the problem goes
away <EM>completely</EM>, until I shutdown and the engine gets cold
again. I barely even recognize that SES light... hardly ever see
it. Driving on warmer days never sees a recurrence of that mid-period
cutting-out, and idle is smooth as is the rest of drivability. Warm
start-ups see a few moments of that IAC-hunting, but the rpm-sweeps are only
on the order of 500rpm and the whole anomaly goes away in about 30
seconds. I've NEVER encountered anything like this in my many years of
wrenching! Now, it's time for some wretching!! All that ever
gets logged in the way of a trouble-code is <STRONG><FONT
color=#ff0000>44</FONT></STRONG>... not too helpful!</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Naturally, I
replaced the O2 sensor-- no improvement at all! Everything described
above instinctually told me this was a weird thermal transient in the
injector-drive circuits or else the MAT, CTS or MAP I replaced (for the hell
of it) 3 years ago needed to be switched again. So I <EM>did</EM>...
one at a time to see if I could fault-locate the culprit that way. No
dice! I'm running out of hardware to replace! I've even tried
setting that 10-to-1 Chip to different settings, but the same nasty behavior
persists-- the engine's as well as my own!</FONT></DIV>
