Tune Up Questions

Hey guys, I have a 2000 GMC Yukon XL with the 5.3L V8 that I'll be doing a time-up on soon. I was just wondering how often I have to change the ignition coils/coil packs. The truck currently has around 130-ish thousand miles and they haven't been replaced as far as I know.

Re: Tune Up Questions

Alright, thanks for clearing that up Truckdude! And yes, I'll be using AC-Delco plugs, I usually use those on my GM vehicles.
