EA82 mpfi series 1 of 85 and 86 had the unit on top of the thermostat housing on the inlet manifold and sounds like this is what you are after ? It is the fast idle air supply that bypases the throttle body feeding metered air to the cylinders for cold start fast idle. Might actually be called the FICD - fast idle control device. I think EA81T also had this same. Check the hoses for brittleness and soundness, I have replaced with 1/2" heater hose, also bypassed the bypass and not even use it - just needs a bit of play on cold starts like a carby car with a shot choke
FICD is more a valve than a sensor, well, it is not a remote sensor for anything, it is all in house in there with just power and earth conns via ECU ?
We want pics !! of the whole car and lots of them please
