Right I've got a hissing near brake pedal car is a corsa with a C20XE in my brake pedal seams harder and also on idle the car is more pulsey revs go up and down but not by much also when accelerating its a little lumpy put the harder I accelerate the more the hissing stops and car rubs smooth so I'm thinking a vacume leak or servo going but what do you lot think
Cheers

Check the vacuum hose. Spray wd40 along it when its idling, if it revs up, there's s leak on the hose.

Update changed servo and all is fine now on my old 1 just above the pedal there is a plastic white like tube thong that is all loose so must have been causing a vacuum leak from that cheers for help lads
