问:释放后油门踏板,车继续加速

一条四车道的高速公路上,我在正确的车道,进入左边的车道,在全油门加速通过一辆汽车。通过它后,我搬回正确的车道和当我松开油门,车子继续——它一直加速!我按和抑郁踏板的全套操作来确保它是免费的,但不做任何改变。在敞开的节流阀,它被卡住了。尽我所能努力学习,然后我把完整的制动压力,试图延缓汽车继续加速。我可以告诉制动故障迫在眉睫,因为他们越来越热。我改变了传播选择中立。在发动机转速限制器暂时占领了,然后定居4000 rpm。虽然是在中性,我继续按刹车停下来。30秒后停止和闲置的引擎降至正常水平。 The throttle seemed to respond normally. After shifting to Drive, I headed to the dealership. Around 30 seconds after starting to the dealership, the “grade braking on” appeared and then went off. It was a flat road and I was going 20 mph and not pressing on the brake pedal. The tow/haul mode was not on. Before I agree to what the dealership finds, would you please diagnose all of this and give me your advice? Thanks.
