If you don't find anything obvious, pull injectors and replace the O-ring
seals.  They are probably due for replacement anyway.

Ran in to a very strange cold start issue this morning on my newly acquired
84 4kq. The previous owner had warned me about it, but the symptoms he
described didnt make sense to me. And, after this morning, it really doesnt
make sense! 

The car turns over but doesnt fire. After letting it sit for a few seconds,
it turns over and coughs, but misses. More turning over and then finally it
fires and coughs to life. Very choppy but after a few blips on the throttle
it smooths out to a nice idle just above 1k rpm. I notice here when I
blipped the throttle a few times it sounded like the motor was bogging, and
the intake was quite  loud. 

I bring the RPM's up to 2k and its smooth, but at 2200 RPM it bogs itself
down and brings the RPM back to 2k. If I hold lightly on the throttle
bringing the RPM up it will cycle this (up to 2200, bog, back down to 2k, up
to 2200, bog, down to 2k etc etc). If you floor it, it just bogs harder.
After letting it idle (which during all of this it's idling very smooth)
30-45 seconds, all symptoms go away. Runs smooth, rev's  up as it should,
all problems go away. There was no smoke at start up..

 I'm definitely stumped.....


Insight appreciated!
