92 Sidekick Hesitation when cold

I could use some advice on a problem I am having with my 92 Sidekick. I recently replaced the cylinder head with a rebuilt unit. The truck runs great except when it is cold. It seems to be starved for fuel at low rpms when cold. If I keep the rpms up, it is ok. I changed the temp sensor but it did not correct the problem. Any suggestions would be greatly appreciated.

same problem here you go to give it gas and it doggs down like its outta gas i need sugessitions on that to i was told fuel filter but that dont seem right cause if thats the case it would do it once in a while and it only does it when its cold
