Petrol consumption

[Craggle]

Hi guys,

Bit of a problem in that my car is suddenly using a lot of petrol. I aint fitted any engine mods or anything so im confused. One thing that i noticed is that the engine sometimes revs by itself! eg yesterday i wapped the car into neutral and put some stuff in the boot for a sec and the car revved up to i reckon 3,000 revs twice, nobody was even in the car. also the exhaust is a little 'throaty' but dunno why this might affect consumption, would it?

any suggestions would be cool
