throbbing engine

[steveeb]

hi guys,

just got in and felt the engine behaving strangely, it seemed to be throbbing, in fact I could feel a vibration while sitting in it stationary, did feel a bit strange coming round the last roundabout. I gave it a few minutes revving while stationary, seemed ok, not like it was missing but still throbbed, any ideas, at the moment i am putting it down to rubbish Tesco fuel??

thanks in advance

I thought tesco used shell!

Could be crap fuel and the engine "hunting". How much fuel did you put in?
