[200q20v] Hot starts

[Allen Swett]

Hi 200q20v Listers,
I've never posted over here, only on the main list.  I've got a relatively
new to me 
91 200q20v Avant which I've been sorting out slowly thanks to the superior
wisdom and resources available in quattro list land....

Car has 110k on it, have replaced throttle switch, O2 sensor, full tune up,
new 
w/p, t belt, pulley, front seals, vaccum hoses.  I don't get any codes, (4444)
But consistently have trouble on hot starts, has never not turned over, but
does take a little cranking.  My question is has anyone else had this
trouble and remedied it with either new injectors, or cleaning and or
replacing the reference sensor.
These are next on my list, but would love to hear any feedback from anyone
who's had a similiar situation.

Thanks in advance for any help.
Best Regards,
