I am at 101,000 miles and would like to do a tuneup. How much should the parts cost for me to do it myself? Other then plugs and wires, what else will I need? Should I go with factory plugs and wires or aftermarket? I was thinking about the E3 plugs. I have a 99 Silverado 5.3 ext. cab 4x4. I need to do a tranny and coolant flush to.
Thanks,
