1992 Cadillac STS Idling Problem?
I did the self diagnostic on it and it comes up with code "E030" which the service manual says is "Idle Speed Control RPM Out Of Range". I know what this is, it's a little screw-like control that an arm sits against when you aren't pushing the gas pedal. The screw moves in and out but doesn't return to the same position everytime to give a constant and correct idle speed.
I've also heard that those codes are to be used as a guideline and are not necessarily what's wrong. Any ideas or suggestions as to what else could be wrong would be greatly appreciated. Thank-you in advance.
