TUNE UP

2003 Hummer H2

Engine Performance problem
2003 Hummer H2 V8 Four Wheel Drive Automatic 87,000 miles

I just figured that there are a few things that I should do as far as a tune up. I do all the normal things like grease and oil. Should I do Plugs, Wires, . Any suggestions?

With 87k miles on it and not knowing when everything was changed last, I am going to list some things I changed on my vehicle around that odometer reading.

Plugs
Plug wires
Oil
Fuel filter
Air filter
Checked tire tread
Checked suspension (grease, wear/tear, etc.)
Timing belt/chain
Checked battery and alternator
Checked coolant for correct color/level
Had all around alignment and tires rotated.

Hope this helped.
