daddyshatch

I just swapped a d15b into my 92 lx and am having some problems. When I first start the car it won't stay running and after about about 20 secs of pressing the gas to keep it running it just clicks and stays running. It is also running kind of rich and was smoking when we first got doen with the swap. I am thinking it may be the IAC but any feedback would be great. Also the d15 from the lx had no MAP sensor and the d15b requires it. Should I get a wiring harness from a cx or dx?
