Oh can I ever relate to your experience! I was driving and my car reved up and was really roaring. The roads were spotty ice and the edges were worse. I put the breaks on and was sliding. Trying to find a place to stop without ice. so I could shut the thing off and get off the road. Two lane traffic and trying to avoid everything. Did stop at one point but when I started again, then I was back at it. Stopped at a motel and called AAA. They said they would charge because I was over 30 miles from home. I did have it towed and they never found the problem, but I can tell you it is a sure way to get your adrenaline running.
