Dennis, <br>
<br>
I had the same problem with the screws in the distributor cap and that
will cause the problem you are having. I know it is hard to get to that
screw, but what I had to do was just get one screw started a couple of
turns and then get the other one going and then be sure I had the cap
pushed down to the bottom and seated in position and then tighten each
screw a little at the time until I had them both tight. I don't know
why it is so hard to get the cap in position, but it is and when you
get it you will know it. I had to walk away a couple of times because
it was a job for Houdini.<br>
<br>
Hope that helps,<br>

Hey Dennis, I'm 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>

I have <em>tried</em> all those diagnostic trees-- even a couple of

reason I haven't fooled with those things is that the misbehavior
complained of is SO PREDICTABLE and only afflicts COLD-START-UP

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

<div> </div>
<div><font color="#000080" face="Palatino Linotype" 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 color="#000080" face="Palatino Linotype" 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 color="#000080" face="Palatino Linotype" 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 color="#000080" face="Palatino Linotype" 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 color="#000080" face="Palatino Linotype" 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>
