TAKE VECHICLE TO AUTO ZONE OR ADVANCE AUTO PARTS THEY WILL CODE SCAN YOUR VECHICLE FREE.SERVICE ENGINE SOON LIGHT COMING ON COULD MEAN EVAPORATIVE LEAK OR CYLINDER MISFIRE.BUT AUTO ZONE WILL SCAN IT AND TELL YOU WHAT TROUBLE CODE YOU ARE GETTING.

Have you tried replacing the ignition coils? If they get old and stop working, or if they're damaged, they won't send a strong enough spark to the plugs. AutoZone (I think) apparently does free diagnostic codes for a check engine light. I don't know if you have a check engine light on or not, but maybe the light burned out? It might be worth a try to call them and ask if they can check the codes for you for free.

Ok this may be something smal that may be simple to fixs; your plugs are in the wrong cylinder?

Check Your gap size .060 (In thousandths of an inch)

Im not sure of the size of engine please look below for your make?
