The warm-up regulator supplies extra fuel to the car to allow it to warm up under the proper mixture conditions. If your car is having trouble starting and running during warm-up, it may be time to replace the regulator. It is important to keep in mind that the warm-up regulator controls fuel pressure all of the time - even when the car is running and warm.
