What do I set the spark plugs on in the car? on 2001 Ford Escort

I just put new plugs and wires on my car, but it still runs badly. what do I need to set the plugs on to get the car up and running?

if you buy Motorcraft spark plugs at Autozone. you do not need to gap it is pre-gap. I did mine and I thought I need to gap it but i didn't. dont tighten the spark plugs so much. check the burn of plugs if its dark or burn you got issues
The spark plugs needed to be "gapped" properly - however, i'm guessing that there is some other issue occuring here causing the engine to run poorly. Testing needs to be done to determine what the cause of the problem is.
