Hey Guys.... newbie here.

I need some help... I have a 2002 [COLOR=blue !important][COLOR=blue !important]Silverado[/COLOR][/COLOR] Z-71 w/ 117K... although I have never gotten great mileage, recently it has gotten HORRIBLE!!! (It seems like it happened all of a sudden). Has anyone else noticed this? What can be done? I have never done a complete [COLOR=blue !important][COLOR=blue !important]tune [COLOR=blue !important]up[/COLOR][/COLOR][/COLOR]... maybe time for new plugs, wires, etc? I'm not sure... just looking for ideas, suggestions, and help.

Thanks... [COLOR=blue !important][COLOR=blue !important]great [COLOR=blue !important]site[/COLOR][/COLOR][/COLOR]
