ka stalls

[SR240DET]

my ka stalls out after i drive and come to a stop not all the time just most of the time, and somtimes it will quickly buck or hesitate just cruzing. So far i have replaced/checked: coolant temp, tps, mafs, air filter, fuel filter, knock sensor, vacumm lines, spark plugs, cap, rotor, timing, and break booster holds no vacumm

my ecu doesnt throw any codes and when i drive, about 75% of the time it will stall when i press in the clutch and/or brake to a stop.

i guess my question is will a leaking fuel injector, o-ring bad,and bad break booster cause my stalling problem? thanks for any help.

try cleaning your iacv. this could account for the stalling when you come to a stop at normal operating temperatures
