[auto k12 micra strange acceleration issues]

getting some really strange acceleration issues, but only intermittenly

 

randomly when pressing my foot on the accelerator, im getting odd on and off acceleration as it i was tap dancing on the pedal, ive noticed the rev counter also going up and down

 

any ideas what this could be

 

ive did 108k miles on it and its serviced every year

[do i need new tyres?]

ive noticed cracking on my car tyres

 

should i get these replaced?

 

sorry if the pic is warped, tried to shrink it

[2008 Micra Acenta Cruise Control Help]

hi, it aint cruise control unfortunately

 

if your travelling at 30mph and you press and hold the button on the steering wheel, it sets an audio alarm if you hit / go over 30mph

 

i found this out on my acenta when i thought it was cruise control :(
