ok so only noise coming from engine bay sounds like its coming from injectors. its probably them right?
use 93 is all i can say.. changed out 2 rails so far..
id replace them ive seen a rash of ka injectors dieing recently and its only going to get worse as they increase the amount of ethonal in gas
injector ticking is normal... they all do that , it shouldnt be really loud , but you should be able to hear them.
