Can anyone tell me what this part is called? Looks like a ground block but I don’t know the part name. Threw a belt and broke the one off the passenger side, now throwing a code for running too rich. I know it has to do with the injector harness, any help would be greatly appreciated!!!

 

those are just RF isolators to keep RF frequency from interfering with the rest of the car. Highly doubt that will cause your rich code
