this piece is connected to a vacuum line. I checked the line it has suction but the wires on the part are arcing and when it arcs it shuts the motor off. I need to know what this part is so that i know what part to tell them i need. thank you for any help in this matter.
It's the purge solenoid for the EVAP system. It opens at idle and while cruising to evacuate the charcoal cannister (part of the venting system for the gas tank).
One side of the solenoid will have constant power and the other will have a modulated (via the EEC) ground.
