type 44 question (5k/100/200)

[JordanVw at aol.com]

car is a '86 5kT.  first of all, thanks for those who helped with the 
radiator questions..i couldnt find a metal end one..so i just went with OEM..  
hopefully it will last another 10 yrs.  car runs alot cooler, and fan doesnt come on 
all the time. i must have had some blockage in the old one.  

anyway im having a prob with rough idle when i first start it in the morning. 
 i removed and cleaned the ISV , didnt help..i replaced the ISV with one from 
one of the 86-91 VW Vanagons  i had laying around (yea the type44 uses the 
exact same ISV as a 86-91 Vanagon!)  and that didnt help either.. 
problem is this:
start car, and rpm's drop real low, idles like crap..continues to do so until 
i shut it off, then i restart, and it idles fine.   its just that initial 
time i start it, it idles crappy.   its like shutting it off and restarting it is 
resetting something..  any ideas?  injectors leaking down? cold start valve?  
i dont have a problem at all during the rest of the day, car starts fine, its 
just when it sits for more than 12 or so hours..  anyone know?
any help is appreciated..
