Hi. I need some help with my 94' c1500 5.7L. I'm trying to do some maintenance to my truck so that I can get some better gas mileage. I can't figure out how to replace the pick-up coil? I took the Dist. cap off and the rotor already but I can't figure out how to get the next piece off which I believe is a dust cap. It is metal and a brass color. I can see the pickup coil right underneath it but can't get to it.
I heard that replacing it will give better gas mileage. Is that true. My truck has 166,000miles. I also have new rotor, cap, and wires.
I'm in a bind because I already started the project but can't finish it. Help
