Anybody know where these two hoses go to. One from the throttle body is located to the left of the tps sensor, and the other one is between the iac valve and the tps sensor and is connected to hard a emission hose which goes into a connector below the distributor but the other end of the actual rubber hose is cut.

 

the connector by the dizzy is the intake manifold vacuum treeusually it went to the cruiose control servo and another to the modulator valve on the tranny if so equipped and another to a vacuum can either on the firewall up as high as the wiper motor, or in the front corner of the front clip down low


if you tell me exact year make and model and engine then i could scan vacuum diagram from my book


good luck

 

The car is a 1985 Camaro Iroc-Z with the 305 Tuned Port Injection (LB9).
