My daughters 90 Legacy would not idle correctly.

Pulled the iac off my spare car and gave it to her.

Now her's is doing fine. The one from her car needs attention. That bad one is now mine. Any suggestions on solvent soaking? Seafoam? Cheap gin? How do I bench check this thing? Even used they are not cheap.

Ideas??

tnx

When my car would not idle correctly I asked a tech at the local dealer how he cleaned them. He said he just sprays cleaner in the hose going into the iac. I did this and have not had a problem since.
