This past weekend I did routine oil/filter/spark plug change. At first we forgot to gap the spark plugs the correct way so the truck was not runnig smooth for about twenty minutes when we realized that we had to gap the spark plugs. After gapping the spark plugs the truck began running fine but now the check engine light is on. What could be the problem?

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
