one of the sensors plugs into the IACV and other plugs into the IAT on top of the manifold. They both reach ok for me.

The thing is...when i have all the sensors plugged in (MAP, TPS, IAT, and the IACV) the motor idles at 3000. When I unplug the IACV it goes down to 1000. If i take the IAT and plug it into the IAC, it also idles at 1000. But when I have the IACV plugged into the IACV it wants to idle at 3000.

So im really not sure what the problem is.
