This is just more of an FYI reminder for those not in the know and DD your G8, especially if you are getting up over 60-80k miles on your G8. I just hit 107k miles and realized I hadn't cleaned the MAF or TB in about 40k miles. Holy crap did it make a difference. There was a ton of carbon buildup on the TB. It took about 20 minutes to disassemble, clean, let dry and re-assemble. The throttle response change was immediate and noticeable. I was also getting a little bit of a rough idle, which is another telltale sign this is needed. It costs about $10 in cleaning fluids (MAF specific spray and TB specific spray). My MPGs also have jumped back up to normal, about a 1.5mpg increase!
Some basic pointers for those who have never done it.
Do not touch the finite wires in the MAF with the spray straw or your hands...or touch it with anything.
Do not spray the MAF while on the car, just remove it and let it sit on a towel to dry. Do not dry it with a rag, just spray it and let it sit for a few to air dry.
When you clean your air filter is a good time to do this. It really could/should be done every 15-20k miles, but I let it slip
