High idle could be caused by low coolant level

原文:
1, an overview of The idle air control valve in your Vibe contains a coolant passage to enable it to operate more efficiently at cold temperatures. To work properly, there needs to be a Resilient Seated Gate Valvesgood supply of coolant passing through the valve’s internal passage. Something as simple as a low coolant level could cause a longer than normal warm-up of the valve. Check to make sure the coolant level in the radiator and/or overflow tank are at the proper level. If the coolant level is good, check to make sure that the coolant passage in the idle air control valve is not restricted. Q: I heard a noise coming from my 2000 Chevy Suburban after I turned the engine off. I looked for the source of the noise and I found that it was coming from the ABS pump. Do you know why this pump is running with the ignition turned off ? – David, Dolton A: The ABS pump is controlled Check Valves by the electronic brake control module. There could be an internal failure inside the module. Have a technician perform a thorough diagnosis of the system. It’s likely the module and the pump (since it has been running excessively) will need to be replaced. Q: I own a 2002 Chevy S-10 pickup truck with the 4.3-liter V-6 engine. It’s been hard to start for the past three months. Now the truck won’t start at all unless I pour gasoline directly into the throttle assembly. Once it starts, though, it runs fine. I had the fuel pump checked and its pressure was 45 psi. The shop said I needed new fuel injectors and it would cost around $800. What’s your opinion? – W.A., Marengo A: I have good news and bad news. The bad news is that the sequential central port fuel injection system in your truck, as in many other General Motors trucks, has Safety Relief Valves been problematic. The good news, though, is that according to bulletin No. 99066F, a special policy covers the system for a period of 10 years or 200,000 miles, whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. Repairs (by your local Chevrolet dealer) should be made at no charge. This special policy applies only to repairs requiring SCPI system servicing, injector cleaning and/or fuel injector assembly replacement. Save the $800 and make an appointment with your local Chevy dealer to get your truck fixed.

空闲您盛传空气控制阀包含一个冷却通道,使其能在低温下运作更有效率。 正常工作,需要通过阀门的内部通道的冷却剂通过良好的供应。东西作为冷却剂是一种低层次的简单可能导致超过正常热身的阀门。 检查以确保在散热器冷却液级别和/或溢出坦克是在适当的水平。如果冷却剂水平是好的,检查,以确保在怠速空气控制阀冷却剂通过不限制。 问:我听到了一个声音从我2000年雪佛莱郊区后,我转过身来关掉引擎。我寻找的噪声源,我发现这是从未来的ABS泵。你知道为什么这个泵是与点火运行关闭? - 大卫,道尔顿 答:中,ABS泵是由电子制动控制模块控制。有可能是一个模块内的内部故障。有一个技术员执行的制度进行彻底的诊断。这可能是模块和泵(因为它已经运行过分)将需要更换。 问:我有一辆2002年雪佛兰第S - 10皮卡车的4.3升V - 6发动机。这很困难,开始在过去3个月。现在,卡车将无法启动时,除非我倒入汽油油门直接组装。一旦启动,但是,它运行良好。我有检查燃油泵,其压力45 PSI问题。该店员说,我需要新的燃料喷射器,这将花费约800元。你对此有何看法? - W.A.,马伦戈 答:我有好消息和坏消息。坏消息是,中央的港口顺序燃油喷射系统的车在其他许多通用汽车公司的卡车,一直是个问题。
