Yesterday morning I pulled out of my parking lot and my car started acting like it was on a sheet of ice, which is what I thought at first because it was very slippery out. When I stepped on the gas my engine would rev and the numbers would increase on my speedometer but the two front tires would not be spinning. When I took the foot off the gas it would idle and move slightly forward, as it normally would. I was able to have it move slowly to the side of the road. In a few hours, I went back out and it worked fine. Any thoughts?
PS- No recent bumps, accidents. Etc.
