RE: rough ilde
The idle motor is located under the intake manifold.It looks like a cylinder with 2 hoses going to it.It also has a plug going to it.
Im not sure what year or exact type it is.Look on the passenger side the older cars have a green wire for the O2 sensor.Where it plugs in there is a spade connector.It is plastic on one sdie and a rubber boot on the other..Using a Volt meter put the positive lead on the green wire.Then put the other to ground.Once the car is warmed up the voltage should move up and down.From 0 volts to 12 volts.If it doesn't it is bad.
