My mileage has dropped a few points lately, from 25 to 23 highway, so I pulled mine out.

Good, bad, or ugly? (140,000 miles)


I also regapped my plugs. The front bank was up to .066 but the rear bank was all at 061 or 062. They might still be original but they all still look good.

With 140k miles, you got at least 60k more than you should out of it. Without a doubt replace it!
