Hi
I have a 92 Cadi Seville, and one day when I was driving it, the car like took off all by itself, and the brake pedal was hard as a rock, and the RPM's where in the red area I had to down shift and slam it into park to stop, my boss thought it was the Vac hose, but he checked it and it ran fine for him, but today it was doing the same thing, and when I start the car it sounds like it either has water in the gas, or its skipping, no check engine light and i put dry gas and stabilizer in the tank. What could make this happen that one time, then go back to normal for a while then it happen again?

Check the idle air control valve and the throttle position sensor-also clean the throttle body-
