Firstly, i can hear a chronic tractor/diesel sound near the cam belt, so my first guess is a buggered VVT pulley, but when i did the test on it... nothing changed, i applyed 12v to both pins on the vvt solenoid (this is the correct test ay?

Secondly i can hear a hissing sound coming from near the top right hand side of the rocker cover, around the throttle bodies, i can only hear it at idle, and my cars idle is buggered and hangs around 300-400 but sometimes will restore itself to just under 1k ( all so confusing


Lastly after all this, my car seems to have lost its pony's and this wasnt a gradual thing, it just happened. it felt like it had no go. i think the best way to describe it is like the engine performing as if it was permanently cold, performing like it would if u just started it on a cold as day and floored it up a hill.. and i think ive lost vvt, ie it never kicks in

Thanks to any1 who can help
