问：汽车犹豫不决，在闲置的摊位，P0102代码

我的车走了220,000英里。破折号显示了检查引擎的灯。当我以55英里 /小时的速度开车时，汽车开始犹豫。另外，它偶尔会在闲置时开始停滞。我已经阅读了代码，并且弹出了P0102。我在汽车上进行了很多维修，其中一些包括：MAP传感器更换；MAF传感器更换；电线，火花塞，燃油滤清器，燃油泵，燃油压力调节器更换；EGR阀，PVC阀，真空线和线圈包装；油门身体清洁； fuel injectors cleaning; oil changed. The transmission works fine. The car has no leaks. It doesn't burn oil either. There is no misfiring. I had the wiring harness checked and it's good. The engine has not shut off. What else can I do to prevent the car from stalling and hesitating?
