ARGH! Wierd UrQ "idle" habits... MC people, help please...

[Michael Williams <urquattro@surfree.com>]

hey all, this is wierd.  It hasnt happened to me in a while, and i know 
why now.

Anyway, my EM is warped/cracked, whatever, but i just found out yesterday 
that the number one cylinder was also affected by a broken stud and loose 
locknut.  

Prior to that investigation, i had noticed a misfire, which i had written 
to the list about a few weeks ago, and got nothing back.  Mostly at idle, 
gets more severe as the car idles longer.  So i systematically took off 
each spark plug wire while the car was running to see if i noticed a 
difference.  Every plug, except number one made what i thought to be:  
"the standard difference."  Where the engine idled roughly, etc.  Number 
1 produced some wierd effects.  When i removed the plug, the engine 
suddenly reved up, maybe to 2000 RPM, bounced between that and maybe 1500 
and then settled down into an idle that didnt sound all that much 
different than when the plug was connected.  BTW, the bennetts installed 
those nology wires with the wierd ground braids and such, so i dont know 
if they could be a cause...

The plug was still getting a spark, as while i was putting the plug back 
on, it arced a couple times and then when it made a connection to the 
plug itself, it reved up slightly, and then fell into a "smooth" idle 
again.

Anyway, then later on, i found that the number 1 cylinder EM was messed 
up, so i realigned the gasket, tightened the 1 remaining stud and then 
started the car.  It was noticably more quiet as far as the ticking goes. 
 

But now, whenever i start the car from cold, it almost dies for the first 
couple minutes.  It will start up, and then immediately die the first 
time.  Then the second time it will start up, and then fall into a vry 
low idle of maybe 250rpm.  Keep in mind that it was idling and starting 
fine all the time before i changed the seal of the EM.  So then after it 
warms up a bit, it does the exact opposite: it revs WAY too high.  It 
constantly revs around 2500-3000 RPM now, anytime its supposed to be 
idling.  Again, the only change to the car i made was sealing up that 
number 1 cylinder EM again...

Anyone have any ideas?  I cant pull any codes from the thing because the 
bennetts have this little two pin terminal that comes out of the dash 
that they hook up some box with an led to and that tells them the codes.  
I dont have one of those boxes.  Its the yellow wire and some black wire 
if i remember correctly going to it.  Anyone know how i could pull the 
codes from something like that??

thanks in advance everyone.

later...
