I have Civic '94, D15B7, manual transmission.
I am having problem with warm start. Cold start appear to be OK, however warm start is very problematic.
That happens usually when go somewhere and make stop. After few cranking enginee somehow fire up, and running on high RPM like when you start enginee in very cold morning, it has very oxigen enriched mixture. On idle tend to shut down when push gas pedal, let say I "force" enginee by slowly and gradualy pushing gas pedal to accept more gas. When I put in first gear the car perform badly - no power to pull vehicle forward and also has tendecy to shut down.
Any clue or idea what could be culprit? Thanks in advance!

 

I would get a fuel guage on there and check the fuel pressure.
