So i took the car to pep boys the other day to diagnoss this terrible idle problem and check engine light that ive had for some time and I noticed tonight(2 weeks later) when i opened the hood that this wire was laying loose. My car was dead in my gym parking lot despite having a new battery and my engine light has come back on as well. I dont remeber seeing this wire and im assuming it doesnt have to do with my current problem but id like to know where it goes.
