    Do you need to change spark plugs after carbon tracking?

    A few weeks ago, I noticed my engine would "stumble" in drive when waiting at a stop light. It would do this a few times, but no check engine light came on. Eventually, I connected my scan tool and found out cylinder 5 had 20 misfires. I changed all sparkplugs 20K miles ago with OEM Double...

    FYI, Napa Full Synthetic is rated SP

    I'll try and post a picture, but I purchased a quart of Napa Full Synthetic oil since it was on sale. I looked at the back and saw that the donut mark said API SP on it. Which includes the specs for SN+ and SN. The last time I bought Napa oil a few months ago, It just said API SN on the bottle.

    I had my tires rotated today at Mavis discount tire. I was watching the tech and saw he used a cordless impact to tighten the lug nuts. I assumed he set the torque setting on the impact to something reasonable like 100ft pounds. The shop had torque wrenches and a whole poster about lug nut...

    So after randomly looking under my car the other day, I saw an oily substance on my right front tire. I looked closer and saw that my caliper was leaking. I felt no difference in my brake pedal. My fluid did get a little low, but I thought that's because of brake pad wear I have a GMEPP...
