solenoid? sensor? help!
 

hello all. i have a 89 chevy caprice wagon. 307 5.0. i have a wired plug on the top, lower left of my carb. i was wondering what it may be called. i have asked mechanics of all walks and no one can figure it out.

the part that sticks out the car looks like the picture in the link. the blue part. so it may be the idle speed control. i just need to be sure.

Acdelco 17111102 Carburetor Idle Speed Control Solenoid~1989 Chevrolet Caprice CLA

any help would be tremendously apreciated. also where one might find that part, other than from above linked web site. thank you.

That is a Fuel mixture control Solenoid also known as a (feedback solenoid).
If you need more info regarding it let me know.
