Your fuel injectors are small electrical valves that open and close very quickly allowing a certain amount of fuel to be injected with the air your engine is drawing in. Newer GDI engines have a totally different style of fuel injector and these fuel injectors make an engine ticking noise especially on cold start up. 10 Causes of a Car Losing Power when Accelerate. The ticking will go faster if I give it a tiny bit of gas so I believe this is a good case for a ticking fuel injector.

With this system, when decelerating (switch 1 close), the fuel injection is disabled until the rpm goes down to 2000rpm. PEA chemistry can also be found in fuel system cleaners from STP, Gumout and Valvoline. But at other times while it is warmed up it will be noticeable.
