问：我的卡车不是正确的，正在忙很多汽油
我有1995年的Isuzu拾音器2.3 L，我一直遇到一些空闲问题，首先我的车跑了一段时间后不会闲置，然后开始运行非常丰富。所以今天早上我开始了它，直到l温暖，我才会闲置，然后我稍后出去，闲置几分钟了，直到汽车完全弄下来，我读了上面的故障代码异想天开，它读取代码12和34
我的汽车有240000英里。
我的车有手动变速箱。

检查代码时，代码12总是会闪烁。关闭引擎后，没有点火脉冲，因此代码12是正常的。代码34与地图传感器有关。歧管绝对压力。基本上是一个真空传感器。由于MAP传感器甚至真空泄漏，可以设置代码。失败的地图传感器或真空泄漏可能会导致艰难的启动，粗糙或富裕的运行，甚至停滞。真空泄漏可能是由于损坏或分离的真空线，甚至是电动制动器助推器内的真空泄漏（如果配备了动力制动器）。如果真空读数都很好并且没有发现泄漏，则更换地图传感器可以解决您的问题。但是，您可能想拥有一名经过认证的技术员正确诊断故障代码to be certain there is not another cause.
