当我停下来按下煤气踏板时，我的车关闭

Hello, Welcome to Just Answer My name is \*\*\*\*\* \*\*\*\*\* I've been an automotive engineer since 1996 and together we're going to solve this issue. This could be an airleak after the airflow meter, any air dragged in here isn't 'seen' by the ECU and so not compensated for and can lean the engine out causing rough running. As its a mechanical fault it may not to turn on the fault light and you can sometimes hear a 'hissing' noise with the engine running. Check the hose clips for tightness and inspect the trunking for any cracks or splits and also all the vacuum system, the small bore pipes and fittings for cracks and missing parts. The best way to locate a leak is to have the engine running and warm and then spray lighter gas /propane or brake cleaner around each joint in turn. If the engine rev's up you've found your leak. Now you might think that spraying lighter gas around a hot engine isn’t wise, however the flash /ignition point of gas is about 400°C so you need a naked flame or spark to set it off and I’ve used this method for many years without incident. Work your way through each possible joint one at a time and you should find it. I use a slightly flattened piece of brake pipe and some rubber hose from the can of lighter gas to provide a spraying 'wand' and allow a direct blast of gas into each area, especially those difficult to reach with large implements. Air leaks are very temperature dependent as gaps can open up as things expand with temperature so depending on how the leak occurs ( on a hose joint with a clamp expansion will help seal and on a vacuum hose expansion will make a leak worse) so leaks can be better or worse as the engine warms up 1 vacuum leak path that you won't find with the above test is if the brake servo is leaking so try clamping off servo hose to see if this has any effect It’s also worth getting the fuel pressure checked as if this is low due to a blocked filter or faulty regulator or even a poorly pump will all result in insufficient fuel being delivered to the engine

由于失败的不同，这种类型的问题可能会被累积。我们需要通过消除诊断方法从共同的问题开始共同努力：在您的情况下，您的问题听起来像是您的[催化转换器]（/toppics催化 - 催化 - 连接器honda/）。那是最坏的情况。[排气]（/主题 - 偏心/）积聚或超过排气烟雾无法通过，因此使气体气体会导致排气急流，但在CAD中堆积...这意味着几乎没有排气。取出二次[O2传感器]（/topics-o2-sensor-honda/），一个通向排气歧管的二次[o2传感器]，然后如果它运行，则听起来很大，但如果您给它燃气，听起来像您的PM和PM的速度汽车更大的可能性。不要将O2传感器拔出的火焰通过那个孔来，因此也可能很危险。请检查一下，让我更新我们将解决。
