Morning, yes I've got a scan tool of sorts it an Innovate OT-2 that links to my IPhone via an App called "log works" however of all the channels listed that it's reading I can't find one with "IAC" in its title?
Regards the rubber hose it's a short length that feeds the IAC directly from the Roe air filter and bypassing the throttle body, when I have the bonnet up and am opening and closing the throttle I can hear air still being sucked through this tube as the revs are dropping as if the IAC is closing too slowly and to be honest I didn't expect the IAC to be open when the throttle is opened? When I clamp this hose shut with some grips the revs are really sharp and drop as you'd expect.
I notice that the throttle is hanging for a second or two more when the truck is warm than cold, any advice would be useful.
One thing that I must mention is that to fit the Roe supercharger I had to lengthen the four cables to the IAC, I am 99% sure that I joined them correctly but two are colored very similar and I'm wondering if that could be an issue? I will swap them around tonight and report back....
