I dropped the rearmost washer for my throttle cover. It fell near some clip with wires coming out (injectors?) and is to the right of the coilpack for #5. I managed to save the hexbolt with my magnet grabber but can't find the washer. Will it be alright or should I go looking for it? I am just hesitatant to take apart my upper plenum to look for a tiny washer.
