I noticed yesterday that my car runs no differently with the ISC unit connected or not.
If I have the car in self test mode, the idle will increase as usual, and will drop if the ISC is removed, however, when the car is not in this mode, there is no change. This suggests that ISC is not stuck.
I tested a constant 13.5V at the ISC on normal Idle.
So my question is, should I notice a difference in at idle in normal mode when connecting/disconnecting?
