I am trying to correct a miss problem at idle and low speed. I recently saw some injectors for a Ford Mustang that are the new type injectors with 4 spray injectors. These are used on the police interceptors and the mustang 4.6 litre v-8s. Has anyone heard of using these injectors in the 635? Supposedly the injectors give a better sprayand with the 4 holes atomize the mixture better. Also the injectors are rated at 19 lbs. Anyone?
