Punto (Mk2/2b) idle issue

[blinked]

Hi everyone looking forward to using the forum, getting tips and advice from you all. I have a 2004 punto active sport but found when its cold it idles rough before settling down, then when i drive it for the first 10-15 mins it seems to lack power or have a flat spot. I've noticed a repair to a split in the air intake pipe and i'm going to replace this but is there anywhere else I should be looking? thanks for any help you can give

Rough idle as in actual misfiring?

If its rough but clears once warm
Id be looking to see what engine sensor is lying causing fuel mixture to be out

Dont even dismount spark issue if no service has occoured on them
