You may have a bad temp sensor that is telling the ecm that it is warm and it does not give extra fuel . This sensor takes the place of the old choke.

try removing the TB and giving it a good cleaning. I have a feeling the TB passages for the ICV are carboned up not letting the air pass thru as needed.
