Golf idling trouble

I've a Golf MK3 1994. When car is warmed up the engine struggles when the revs drop down. There's a popping sound from the carb? On open roads the car is fine.

Just in and around town it plays about. I've changed the plugs, cap, sensor temp, leads. Someone said it could be the coil or mass air sensor, but they all seem to be working as I've had it plugged in.

Could be a number of things, would suggest you try the EVAP (evaporative emission cannister purge valve), and if ok check the TP sensor (throttle position sensor).
