88 80Q won't start or idle when cold unless you crack the throttle

[Geraint Lloyd]

Not sure what kind of vehicle we are talking about.
if it's a1988 80Q then does that mean it's european or is it in the us/canada.

if it's really an 80 is it an 80Q or a 90Q? is it injected or does it have a 2E2 or similar carby thing? depends what side of the atlantic you' re on!

I'm assumung that you are in north america with a CIS-E 5 pot 4000Q, but am not 100% sure.
the euro spec k-jet stuff is supposed to be started with the throttle half open according to the vehicle manual.

you have recieved tips regarding the ISV and AAV, however these 2 devices are never seen together and perform the same function on different versions of the k-jet ke-jet and digifant IIs. 

Need a bit more info
