Have an 87 coupe w/iron duke & auto. Just had another rebuilt engine
installed. Noticed a noise & when I took off the air filter housing the
injector is making a metallic ding, ding sound, Don't remember this with the
other motor. It is also surging then all of a sudden runs evenly then surges
again. But wonder if something is wrong with the throttle body with that
metallic ding, ding noise.
