2005 Fiat Punto idle problem weird noise high fuel consumption with recording

Car: Fiat Punto
Year: 2005
Variant: 1.2 8v
Categories: Running Rough, Starting & Power Loss
I have a fiat punto 1.2 2005 8v model yeah it is my first car but since a month or so now i have this problem where if the car is on idle the revs drop and bounce back up and the car makes a weird noise. and i think its due to this that my fuel economy has been halfed =S

ive changed the throttle body and ignition leads as i heard they were pretty common.
any ideas plz?

heres a little recording of the noise if it helps
