1g eclipse gs dies at idle

[15231_1990gs]

im new to dsms and just bought a 1990 eclipse gs 2.0, replaced the cylinder head and got everything timed correctly, it starts but dies at idle but will continue to run if I keep the rpms at 1k or more, any suggestion is much appreciated thank you

Have you checked all vacuum connections and electrical connections could be one of the sensors or lines

everything appears to be connected minus a little pipe that comes off the back of the fuel rail on the driver side but I don't see a hose that could connect to it
