juddering

[biz69]

when i start my vtr its fine but after about 30sec - 1 min it starts juddering and to me it seems like its gonna stall but does not is this normal as i've never owned a petrol before and the last time i drove one was just over 4 years ago so cant remember.

i dont know if it stops when being drove as i cant drive it till i get tax and i cant get tax till the v5 turns up :wall:

Could have a misfire/or in need of a service.. possibly. How long has is been sat up for not being driven?

its been sat on my drive since the 15th oct before that i dont know as thats when i got it. only drove 40miles

the garage said it had just been serviced before i brought it and they had the timing belt done i think.
