I have a 2002 Z71 with 140k miles. Lately it seems like it might be down on power, but it is hard to tell. We picked up a 2014 Escalade ESV a year ago with the 6.2L 400 HP engine. Either the 2002 Avalanche is down a little on power, or I am just getting used to the power of the 2014 Escalade. If the Avalanche is down on power, any suggestions on what to look at? I picked up a new air cleaner filter but have not installed it yet. I figured I could also replace the fuel filter as well.
It has never had the fuel filter changed, has the original plugs, wires, coils, etc.
It gets regular oil changes between 3k and 4k miles.
What should I change/clean, and in what order of priority?
