Hi there. I have a 1997 P Punto 1.6 Sporting with 74k. From cold it idles well and drives nicely. As soon as it get warm the tick over is eratic from 700 to 1500 rpm and when driven is hunts and misses if you drive normally. If you put your foot down is accelerates normally. It just feels hesitant when driving normally. Any ideas? The cambelt was done at 60k and in every other sense its a nice car. No warning lights on and it passed emissions on the mot last week. No nasty smoke from rear. MPG is still ok.

have u done the normal checks for missfires? sparks ht leads and coil pack?
