UPDATE: 4 any1 who has read my previous threads on the tapping noise/piston slap/tappits distroyed/autoworld(sheffield) :-( the problem has now been been sorted out after 3 years just before the warranty runs out :) it was bent valve guider apparently in the end but i got a brand new complete head on the engine for my troubles along with the pistons etc i have also already recieved.

but,
now the tick over is lumpy.any suggestions what it may be and how to stop it?

Yep seen this before even on new puntos!

Have you had the parameters reset/phonic wheel re-learned.Depending on year could be throttle potentiometer.
 
not sure if fiat's have these or not... my fella's astra coupe had these symptons over the past couple of weeks - he had to clean the throttle body out with some carb cleaner and a toothbrush and clean a few of the breather pipes, he was supposed to clean an ICV (idle control valve) as well but the model coupe he's got they dont have them in or something.

not sure if this will help or not!!! :p
 
cheers for the advice but what do you mean by parameters reset/phonic wheel re-learned and what/where is the throttle potentiometer on the punto? Its an '03 mk2, not the dodgy 'kia shaped' type. :)
