Try the Throttle Position Sensor. Maybe O2 sensor but I'd start w/ the TPS.

You replace sparkplugs,plug wire,tps,map,cap and rotor.Thats good,If the vehicle runs and you come to a stop and it stalls,That is the IAC (Idle air control) you say it ran fine for a week now its acting up, Service the IAC or get it replaced.
