noticed today that it was.... "ripped" or more of proken completely off the housing on my car, and then thought to myself hey i should just pick one up at work and switch it, then i realized..... no idea what it is, most people iasked said coolant temp sensor, well no because thats right next to it, and it has a vacuum line? on it my friend who went to NTI told me its an EFETS or an early fuel evaporation temp sensor, but believe it or not that's not in znet so i couldn't verify any help is appreciated, heres pics
