If your idling has been erratic these past few days and you've even stalled a couple of times at low RPMs, you may have a bad idle control valve. You should act quickly and replace this bad valve or it will make driving your vehicle a really terrible experience. But you have to make sure that your next valve will last years, so you won't have to replace it again for a long time. For the best results, install a high-quality Mikuni Idle Control Valve.There are a couple of reasons why the idle air control valve might fail, but one of the most common is carbon buildup. Over time, carbon accumulates in the valve, causing it to stick and ruining the vehicle's idle. Your vehicle may suddenly idle when you're driving at high RPMs or it may stall when you're driving at low RPMs. In most cases, cleaning the valve won't work because the carbon buildup would be too much or it would make the valve unfit for further use. If you want a long-term solution, it's best to install a new, heavy-duty idle control valve by Mikuni that would bring the system back in tip-top shape.The idle control valve by Mikuni is vastly different from average valves because it's made of high-strength materials. It will last years and drastically enhance the idling quality of your vehicle. You don't have to worry about its fit because it's manufactured according to OE specs. The most advanced computer-aided technologies are also used in its production to ensure exceptional performance and precision. It's definitely the replacement part you're looking for if you want to save on repair costs in the long run.
