If the injectors are that loose you should consider replacing the injector seals. I see on most cars they are rock hard and loose fitting into the sleeve. Even when you finally get the injector back in and clipped the seal will leak. The term is "false air" which is a fancy term for air that is getting into the engine and not being measured by the air sensor. As for the clips they can be bent a little to keep from poping off but if any are missing or broken they should be replaced. I would go easy on the Armor-all around the motor. Armor-all contains silicones and if they find their way into the engine by way of the air intake you will contaminate the O2 sensor. Use something like windex which is safer or find another cleaner that doesn't contain silicones.
