IAC and EGR locations
Can someone post pics or give very decriptive details on where these things are on a 3.1 motor? I'd assume mine need some cleaning but I dont know where they are.

IAC is right on top of the throttle body, sticking out of the passenger side and has a 4-wire connector on it. For yours, you will need an allen wrench to remove the set screws.
EGR is on the Passenger side exhaust manifold. It's got a triangular 4-wire connector going into the middle of 3 solenoids. Right next to the heater box and has a tube from it to the throttle body.
