Delphi is an Original Equipment supplier to more than 25 vehicle manufacturers and is the largest and most diversified supplier of quality automotive parts to the global aftermarket. Most injector readings should range between 11 and 24 ohms. Because of their significance on emissions they are warranted in most cases for 5 years or 50,000 miles by the vehicle manufacturer. Some specs may call for 2 to 3 ohms of resistance (typical for “peak and hold” injectors), while others require 12 to 16 ohms of resistance (“high-resistance” injectors). ۞��!�J�BE_s�:R��p�T��&R��~�d�n�u�^��H��IB�S��,U�벵q�4�s�oe��I@��]��l�8l]�3jw�d�!��urF�n�8�N�ז!R��c�dM� #ӫ�s;ѷ�-~̎c=�=�a�5�� v��ϻ;mv�%s��2�,k��cN�a6e��-8�ۺ�;��ז�#��VĆ,u;�{��F�ߧ6�&q��[�7%sǓ�Ԇc�e�Z5��jMkֲ٘1�gg)A��%j��j(��l0�e2��l��V��o�~,��'N�n�O{L��Ԩ�mp7S?�oa��~�UK��s�4��?�b;�7p��? 4 0 obj endobj Tip: You can find the correct resistance for your injectors by searching online or in your vehicle’s repair guide. 1984 Dodge Daytona Turbo Z 2.2L 5-speed 160K miles.
