I found pictures of the replacement parts but I'm not entirely sure where on the motor they are located.

The FPR is in that mess in the valley of the intake. If I remember right anyway.

Yup thats the one. Me and the hubby finally figured it out =) I am pretty sure that it is the Idle air valve thing. When we unplug it, it changes nothing in the idle. I may be wrong but hopefully its not too expensive to replace.

Iac valve is $35. You can try popping yours out and cleaning it off before you spend the money on one. Its just two t15 torx bits I think.

Yes but not in the car, only outside. It smells rich. Im pretty sure that it is the IAC vavle. We took it out to clean it and the spring/coil thing is completely shot. It is so stiff that it sticks.

What do you suggest to clean it with? The spring has no spring left to it, its stiff and sticking...

Carb cleaner or brake clean, it is a stepper motor it should rotate not compress. Chance are you probably will just have to replace it.
