ok i was doing a vac hose job on a friends car. As soon as i got everything back togehter up to the uim i noticed this plug sitting there. I dont remember where it came from and i dont remember taking it off. I sure as hell hope i didnt pop it off somewhere that is going to require taking off the uim ... again



i looked in the manual and it doesent really help out.

^^ the blue shell nad orange connecter.

shop manual sucks

its the egr valve connector, if its a 93-94 california car (all 94's) the egr valve has a switch



mike

its a 93 non cali, so what does that mean? sorry for my stupidity

It goes to nothing. At least it doesnt on my car

so we can leave it off? sounds very good

yup, leave it off. I said the same thing the first time I saw it https://www.nopistons.com/forums/pub...DIR#>/wink.png

Ok my question is, what is that gray plug at the bottom left of the picture? It has the black wires going to it. My plastic connector was missing from one end and it wasn't plugged up. I have a 94 if that makes a difference...

The grey one looks like the airpump connector. If its broken just cut off the connector and either hardwire it or get some male/female crimp connectors.
