First off.. you don't sound dumb.
You are coming here looking for help and we are here to help. Many people that never touched a car before have learned tons here and now are confident working on their cars.
The wires are as important as the plugs. Think of the plug as a light bulb and the cord to the light is the plug wire. If the wire is broken and hardly working..what happens to the light bulb.. it'* going to flicker and not work right.
Do you remember what brand of plugs you put in? We've found and then found research that states Bosch break down quickly in a waste spark system. Our cars have a waste spark system.
