    Hi guys!
    I have a 2010, the car was shaking and I took it to get it checked out and they said it was one of the Pistons miss firing, so I changed my spark plugs but it did nothing, so I decided to clean the EGR valve. When I was trying clean the EGR valve and take the throttle body off the air intake manifold to remove it My Vacuum switching valve assembly that's off of the throttle body ripped off, the wires pulled out of the sensor/plug. I am planning on trying to reattach, but I'm not sure which side the wires go into. No idea what I'm talking about...help.

    Should I just start looking at facebook market place for a new car?

    Nothing like trying to tell a violet wire from a black one in bad light....

    On the bright side, I doubt the solenoid will mind even if you get them reversed. It's not like other things that would care.
