Its a 92 civic hatch with a JRSC gsr swap. The problem I'm having involves a bad idle and the engine stalling out. When stopped and in neutral, if I give any throttle and let off, the rpms drop and the engine either stalls out or just idles very low and almost stalls out. It also does this when moving. For instance, when coming to a stop sign or stop light.

These are all the mods
-AEM intake
-JRSC kit (stock pulley 7psi)
-255 lph walbro fuel pump
-JR fmu
-AEM fuel rail
-440 cc RC injectors
-Hondata s300 p28 ecu
-MSD 6AL ignition
-stock distributor (ignition timing set to 16)
-dc 4-2-1 headers/2.5" pipe/apexi muffler

These are all the parts I've recently replaced
-IACV
-FITV
-MAP sensor
-02 sensor
-spark plugs
-vacuum lines that came with sc kit
-coolant lines that came with sc kit

Any help will be greatly appreciated
