Default lumpy tick over

when starting my cossie it is very irratic on tick over until it reaches running temperature
could it be time for a new set of plugs or are there any common faults that cause this?

Could be the plugs or maybe try a new idel control valve , mines abit lumpy for a few secs when its cold next time you start it from cold disconnect the icv if its the cause of the problem it should tick over at about 700 rpm smoothly....

700 rpm is too low.
