Sounds like you have a faulty TPS (throttle positioning sensor). The TPS offers variable resistance depending on the winding or unwinding of its actuator. When you goose the throttle, or take your foot off the gas, the TPS tells your vehicle's computer where the throttle is. If it is failing, then it could be sending wrong signals to your vehicle, causing it to move the throttle (accelerate) when you are not actually wanting it to.
