305TBI EGR vacuum routing ?
305TBI EGR vacuum routing ?
I have an 82 SC with a 305 TBI engine (E code).
A previous owner removed the smog pump. I am getting SES light. The EGR valve was disconnected and it was bad. I replaced the EGR Valve, but then realized that the EGR vacuum solenoid is missing. I am going to buy a new one tomorrow, but I don't know where vacuum line connections will need to go. There is no diagram underhood and there are no open vaccum ports, so I will have to "T" in somewhere. Can anyone Help me please ?
