No the tapping is from the Evan purge sol duty cycle being commanded on and it normal, they can be loud. Had many Acura customers thing something was wrong with their car but it’s just the purge valve and Acura puts it right by the firewall on drivers side so of course the driver hears it. It won’t change your fuel trim because the ECM is commanding it on and knows to correct for the fuel vapor.
