**Timing belt for cold winter!!**
Yeah!!!!! Timing belt again!!!!!!!!! I just came back from my work, I got a 93 Accord for no start this night. the guy towed the car in. I had it inspected and found timing belt was broken. The vehicle is 195K, woth no record for reaplcing timing belt. when I took out timing belt cover, I found belt cracked all around. Besides, belt will become more harder and brittle when temperature is very low. it won't hold tension anymore!!! it's not the only one I saw today with same problem. I think it's a good idea that if you have high mileage vehicle with timing belt which has not been replaced for while, please start you vehicle carefully. or you can use block heater to keey your vehicle warm. If you get chance, have your timing belt inspected!!!! |

Computer will know the A/F( Air fuel ratio) from O2 sensor. If o2 sensor reading is low voltage, it means A/f ratio is lean. lean means too much air in the mixture. Actually, engine is running very well when a/f ratio is slighter lean. it will produce more power and has good fuel efficiency. We have a strict emission bylaw in North America to control vehicle emission. engine with leaner a/f will produce more NOx which most likely contributes to smog. So modern engine design will let engine run at slight richer to minimize Nox content in exhaust. It means that is compromise between emission and fuel efficiency. Your vehicle will be safe to drive but no good for engine original design purpose because it's running hotter than normal. How to fix it: 1. check fuel pressure at normal idle and high idle. If fuel pressure won't increase at high idle, replace fuel pressure regulator because there would be no enough fuel being injected into cylinders and it will cause lean a/f ratio. 2. If fuel pressure is good, try to replace the pre-o2 sensor. also, if you have no idea about some terminologies,please read "有关汽车氧气传感器的探讨" or " 为大家解答汽车各种故障等问题", or ask me directly. you will know how does engine PCM exactly control A/F ratio. |

ThANK YOU !FAT CHICKEN can you tell me how to check the fuel pressure? Thanks! my problem is the "service engine" light turned on ocasionally, and sometimes it turned off automatically, so I think it should not a very serious problem. as long as I can drive it safely, I am not in a rush to fix it, I think so! Any way, thank you again. you are really a warmhearted person. |

The only way you can do is to use a gauge, hook it up on fuel pressure test port. You might have to buy a expensive gauge which is not worthy for you. |

热心的肥鸡老大。有关氧气传感器的问题请教一下： VW Passat V6 1. 我的车CHECK ENGINEE 灯亮了，上周五在VW的dealer那查出是两个前氧气传感器坏了。于是在他们那换了两个新的（两个是500元左右再加上三个小时人工。大出血）。当时据机师说他们的检查电脑只报到了两个前氧气传感器坏了。可是换了后开了一会CHECK ENGINEE 灯又亮了。今天下班后又到DEALER那去查。这次他们的电脑说第三个（后氧气传感器）坏了，需要换。我就跟他们理论起来。为什么第一次检查时只报告两个坏，现在突然又说第三个坏了。他们的理由是换了新的传感器后，原来剩下的两个中可能有一个不能够工作在FULL CAPACITY，导致电脑报错。请问这样的解释有什么道理？ 2. 如果第三个传感器真的坏了，我不换它有没有什么大问题（如尾气检查通不过）。我看了你对氧气传感器的介绍，好象后氧气传感器不用来做AIR/FUEL的调节。 3. 是不是大多数的原装氧气传感器都这么贵。如果用AFETMARKET的产品（如BOSH的）和原厂的一起用有没有什么问题。 4. 换氧气传感器真的需要很长时间吗？VW dealer干这个的LABOR太贵了？ 多谢！ |

Since you got same problem just after replacement, you should get refund from dealer or you just ask them why they did not tell me the post o2 sensor failed again. I guess they got codes but they ere not sure what the exactly problem it was. they just want to get your authorization and try it. |
