HELP KNOCKING

[$lick]

started the truck up this morning and drove it to the drive way to warm up. ran back into the house and put cloths on and got ready ten minutes later i could hear the truck from the house. walk out side and it sounds like there was a sledge hammer going being used next to it along with the regular idle sound. the truck has 1800 miles on a new motor and pensicola superkit injectors AD's. i know these injectors have horror stories and i have a feeling that its the injector fouling. i just had a tank of fuel put in and its red diesel that my buddy had in his transfer tank for maybe a bad fuel? i need help and i am going to put a video up later..

can you return penns injectors and get your money back? cause i would in a heart beat. help help help help help help
