Saxo 1.1 1999 Problems, with videos :)

[bmxriderj]

Hi, I have a citroen saxo 1.1 1999 plate and have a couple of problems that i am worried, need some advice please Videos that i have taken will be put up for help

I have owned the car just over 2 weeks and the guy who had it before me didnt know when it was last serviced.

1. The car revs by its self and today i was sat at some lights and the car revved itself quite high then low then high again without me touching the accelerator, the car revs itself slightly since i have had it but not been an issue until now.

2. It makes a horrible noise crunch when putting in from first to second and the car jumps sometimes after changing gear, plus when lifting the clutch after changing gear it makes a slight bonk noise. In the video the engine is not running but makes the same horrible noise when driving.
