Idle Control Valve Wiring Problems
I've been having high idle problems with my 380 for a while now. I've had both idle control units looked at, one needlessly replaced, tested and the idle control valve, and tested the wires that go to the idle control valve. When I put a 9 volt battery to the connectors on the idle control valve, it shut right away so I know that it works. I tested the wires that connect to the idle control valve and when the battery is connected but the engine isn't running (the valve should close) there was no electricity going to the valve, with the engine running there was only about 1.3 volts.
The conclusion I'm coming to is that the wires that lead to the Idle Control Valve aren't properly connected. If anyone has had this problem or thinks they know what I need to do to fix it, any help would be amazing. Or if someone can tell me where those wires run so I can check the connection. Thanks.
