Was cleaning up the engine bay a while ago and i noticed the egr valve not connected. Check the diagram and seen that it is suppose to be connected to the egr solenoid and another hose from the solenoid to the carb. Problem is that the solenoid is no where to be found??? And also the bracket where tied up too. Found the egr solenoid online but where would i put it?? And also what is the use of. Ive read that it makes the car run better and also saves gas is this true?
Saw diagrams of it behind the egr valve but i dont see can anyone help?
