156 hesitaion / misfire help required, please!
hi there, ive just started to experience an odd fault with my 1800 twin spark veloce.
it will drive normally under light and part throttle, all the way through the rev range, but ask more of it under heavier throttle, and it hits rough patches starting around 3/3500 revs and upwards.
floor it, and it gets even worse, to the point where it will simply sit stuttering at all sorts of higher revs and it won't pull through it untill you ease of the gas and let it free rev again.
has anyone got any ideas before i start divin' in!
it feels as an older car would if the plugs, caps, or leads were knackered if you know what i mean, but this is all very fresh equipment so i'm hoping i can elimnate them initially, but your thougts please.
thank you very much for any asistance you can offer,
