First time ever on a forum...hope I can get the help I need. I gave my dad a 2002 Silverado about 3 years ago, 4.8 liter. It just started producing a dead miss on the #5 cylinder. Gave it Delco plugs, wires, delco coil pack on the cylinder. Miss prevails!! He's going to swap out the injector next but asked if I could give him a step by step for its replacement. I haven't studied this engine since I gave it to him 3+ years ago...can anyone give me a hand. I would prefer a step by step before he goes gung ho on it taking off parts that don't need to be touched. I haven't found anything online that suits what I am looking for. Can someone help...ALL replies will be greatly appreciated. Thanks.
