[200q20v] carbon on spark plugs

[omllenado]

I usually take out my audi's spark plug and spray it with a carb cleaner and brush the carbon deposits. my plugs Bosch super plugs W7DTC are 3 months old .

What could be causing this?, sometimes after a cold start and rolling out from the parking lot  I hear a popping sound from the exhaust and the engine would eventually die so I rev it to prevent stalling.

I just changed to castrol synthetics and It seems to have tamed the engine noise to a certain degree.
