I'm thinking fuel injectors. Today i pulled into 7eleven for a hearty breakfast on the go and when i was leaving, the car turned over and almost started and died. I know these kind of things happen sometimes and it started up fine the second time (a little rough but i pumped the gas pedal) but I keep hearing these ticks and they make me nervous. My AC fan can be pretty noisy also although I don't think that's related.

Here's another video. When I came back from the grocery store it was louder and much more noticeable.

anything? videos might be not clear enough I guess.

 

I'm open to random ideas that you might have.. it'll help me troubleshoot.
