Easy way to test for a stuck injector/leaky fuel o-ring. Get your car at an idle. Pull each injector plug off one by one. What your looking for is a injector plug that when you pull it, it doesnt effect the idle. Or it doesnt effect it as much as the others did.
You can do the same thing with your spark plugs. Pull them one by one and do the same test. If you find one that doesnt effect idle as much as the others, that means your wire or plug is bad.
