This is my first time posting to this forum. I have a 1987 Touring Sedan, and I think it is of the Deville model but not sure. No mechanic can seem to find "Touring Sedan" in their books.

I have just received a service code E30 which, according to my factory sercie manual is Idle Speed Control circuit error. I am assuming a problem with my idle speed control unit next to the throttle body, but everything lookd OK. Any help with this matter greatly appreciated.
