the gas petal to the floor? Well I notice sometimes went I drive about 45 mph and up the car doesnt know how to idle back down went I stop. Then when I put it in park the idle is so high sound like I am doing about 80mph. Sometimes the idle doesnt settle down until a couple of days. I change the MAF sensor, and I'm going to try cleaning the throttle position sensor.The weather is very hot by the way. But any idea what else could cause this. THANKS
