I would start by removing each one of the spark plugs and keep them in order of the cylinder they came out of, then look at each one to see if there is one that looks different. This would be the cylinder that is having a problem.
You are looking for a dark plug letting you know the injector on that cylinder needs to be replaced due to a spray pattern issue.
Please let us know what happens.
