Idle problem on '90 EF9
 

I just bought an EF but after driving it home, i found that the idle was inconsistant, like the car was breathing, If the picture worked i unplugged that and the idle was normal and drove fine, despite the engine light was on, any one know a solution, Also not a pic of my motor, i would freak if it was that dirty

Try cleaning the EACV (IACV):
