My car would start and run OK until I let it sit for a short time, 10 minutes or so. It would then start and die or just crank without firing. If it sat another 10 minutes it would start again. My guess was that the alcohol was vaporizing somehow. I was forced to test this cause several times when I needed gas and only the alcohol blend was available. Larry
