Yikes...mine stumbled today. I was stopped at a light, with my foot on the brake. I heard/felt a little thump, the idle speed dropped slightly, and when the light turned green, the car stumbled and stuttered when I tried to pull away. I drove about 100 miles today, and it only did it once, but it does irritate me. The OVP must not have fixed anything.
