disconnect negative terminal of battery.
put foot on brake pedal for like, 30 seconds.
leave for half an hour at least.
connect neg terminal, start engine, let run for about 10 mins at idle.

If this doesnt help, check out fuel pressure regulator, dizzy timing, fuel pump health.

you only need to remove the 7.5A backup fues in the under dash fuesbox for 15 seconds
OBDI ECU do not learn idle parameters so idling the engine for 10 min is pointless, disconnecting the battery for long periods of time and turning on headlights or pressing the brake pedal ect is also pointless.
