Hi everyone

I'm trying to finish up my 87 after an engine rebuild. On the front of the
intake manifold I have a sensor, an empty threaded hole and a pipe whereby not sure a hose goes there from. Any pics or help would be greatly appreciated.

sensor on the left provides the signal for the cold start injector, right sensor, coolant temp sensor - signal to the ECM. coolant hose connect to the throttle body.
