Did you disconnect the battery at all or jump start it?

are you sure you put the leads on the correct plug?

IF it was trouble free before you touched it,
then something is amiss.

A pilots rule is to undo the last thing you did !!!

Test both the leads and plugs!

It IS possible you have a crook lead or plug.
IT does happen to new ones.

Put on a rubber glove and start removing and refitting plug leads one at a time with the car running.
If you remove it, and it runs worse then it isn't that one. It will be the one that makes no difference to the way it idles.

If they ALL make it worse, then it ain't plugs or leads.
