What is this sensor that i circled, and i just put an ls in my del sol with this sensor on the IM. My question is where should i hook up this vacuum line on the car. Thanks

 

IIRC that is called a Purge Valve. And you won't need it for your Del-Sol. You can plug up that nipple on it or take it off and plug the hole thats in the IM.

 

dont need it

 

thanks for the responses, i thought that sensor would have something to do with the idle, my problem is my idle is around 100RPMs when i first start it up, then it jumps to about 500. Is there a vacuum line somewhere i need to hook up? Thanks
