My 05 Avalanche that I've had since new now has 112k. When should it be tuned up? Also what plugs, I understand that the plugs that were installed new are no longer available. If not, what plugs should be used?
The truck seems to run fine, I just wonder when it recommended to change plugs and wires. And anything I should be aware of when doing this.
Thanks
Rocky
