Just recently purchased a clean 1972 280SE 4.5 liter. The vehicle is in great shape and for the most part runs like a dream. Just recently I have had an intermittent problem with loss of signal to the # 2 and # 7 injectors. Have checked them with a noid light and confirmed no signal. Have done a continuity test on the wires from the injector connector all the way to the processor. No problems there. Is this a processor problem or should I be looking for somthing else. :?
