I just recently finished a rebuild on my engine. I have a Green Plug (female) that isn't plugged into anything. I don't remember if it was that way when I took it apart. I have a 93 automatic touring California spec car. Anyone know what this plug is? It is inbetween the air pump and the Intake manifold, near the two selenoids that are bolted to the intake manifold.

Anyone have a clue please help. I've checked and rechecked, cannot for the life of me figure out what plugs into it.

thanks for your time

 

shot in the dark, maybe the plug for the temperture sensor on the back of the thermostat houseing?

 

that would be your EGR connector. Since you have a 93 (if i remember correctly) you won't have anything for it to plug up to. However since your california I'm not sure if you actually have one or not. Hope that helps, its 2 in the mornin and I'm tired as crap...see ya

There two green plugs in that area, one goes to the sec fuel rail, It is the gas themosensor, the other is to a water temp sensor.Every one knows the EGR plug is blue.
