    This might be normal but I'll ask anyway. When I turn my heater on the rpms increase. I know this is normal but when the heater is on the rpms increase and decrease at will. I've had my foot on the break lightly while sitting in traffic when this happened once and the truck almost lunged with the increase rpms. Is the normal? Or is there a alternator relay problem?
