Well my rig has been idling kinda rough latly and im trying to find out why, I change the distributor cap and rotor, cleaned the iac/ throttle body, changed the plug wires. So now I just pulled the plugs, im not sure if they look bad or not, there all dry. Heres what they look like, should I change them? My check engine light came on too

I would like you to come see how many I pull out of the box that are gapped wrong. usually too large, and the occasional one that closed in on the center electrode.

I refreshed and now can get the pic to come up, you are using the diamond fire or e3 thingamajiggy. Is the center electrode rouded at the top edge instead of sharp corners? Can't really tell form the pic.
