The reason is to make sure there's only 1 device controlling ur iddling. There's 2 sockets connected to the tb. 1 is tps, another is isc. The one facing the firewall behind the tb is the isc.can u advise me where to unplug the ISCD? wad would the effect on this be on my timing and engine?
When both isc n ficd is connected, both devices will interfere each other. The reason for ficd is, it's a single direction valve when not activated. I don't know abt fitt.
