   , when im accelerating if i go to about 4k revs and let off the accelerator i can hear an electric kind of whizzing sound as it decelrates? also can hear this when i accelerate fast to over-take, any ideas?
   
   The sound's kind of like a toy car crossed with a supercharger :/

   Might be your air intake. Check your Air filter and hoses to see if theres any breaks/leaks?

   Is it easy to do or would i be likely to just fuck it up?

   If you paid someone to do cambelt you wont be able to do it yourself.

   Fair enough, if i took it somewhere how long do you think it would take them to do?

    And also te guy that fitted my cambelt told me i might need a new aux/alternator belt soon, could that be the cause of the problem?
