Rough idling and stalling are typical symptoms of a busted warm up regulator. If you don't fix yours right away, you're going to have some serious headaches in the days to come with your car bogging down every street and highway. As you know, the regulator is a simple but essential device that changes the control pressure of your vehicle with the temperature. It would usually fail due to two causes: foreign material getting lodged in the metering chamber and malfunctioning heating element. Some drivers try to clean their regulators when they turn bad, but this is just a temporary solution to a problem that's bound to wreak havoc in your car. If you don't want to pay bigger auto repair bills in the future because of other parts getting damaged by your bad regulator, better replace it now with a new one.
