For my 1996 Integra(automatic), every time I step on the brakes the RPM would go lower and lower as the car slows down. It feels like it is going to stall since the RPM is very low, like a few hundreds. Why is it bogging down like that? Any way to fix it?
It also happens when I shift to reverse gear. It would go real low before rebounding somewhat.
However, I discovered that if the blow fan is turned on, the RPM would normally go slightly higher.
