JRSC 94 gsr (obd1 b18c1)/problem stalling when rpms drop after giving throttle
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
Please help!

With the MSD setup check your wires inside the dizzy cap...from experience if they chaff (sp?) they will arc and short out and made the idle real crappy.

this is problem i had a while ago and it can be a simple fix if it the same problem cuz my happen after a long trip. and as the time when on its happen more and more... if that is happen with your.. first check and clean the TB and as far as u can reach inside to your IM cuz u car might just be chocking. so make sure u take off your intake and clean it good. and if that doesnt work next can your IAC take it off and clean that too. cuz that what control the air your can get when in idle... first do that and PM me then let me know... ill tell u what else to check

I don't know if it would apply to you, but I've heard about people having to upp the injector duty cycle when they got a really light weight flywheel. Letting off the throttle will make the flywheel drop rapidly, more than it would with the stock FW because it's heavier and has more momentum.

if you switched tps and map sensor this can happen, make sure you plugged them in the right spot, the two sensor are located on throttle body. Try switching them around, Good luck

LOL the same exact occurrence for my setup as well. And yes the sensors were swapped around, and after the proper switch around, drove like a charm.
