I had sprung a coolant leak that came from the heater core pipe, which involved taking the intake manifold off. I just got it all back together tried starting it, and it sputters out the first start or two. After that, it finally starts and stays running, and the RPMs go up and down repeatedly without touching the gas pedal. Also, pressing on the gas pedal does nothing, just keeps on doing the aforementioned rpm dance. I have a feeling this has something to do with this wire that I couldn't find anywhere it could plug into, I'm hoping that is the culprit. I have no idea what it goes to, or even how to search for it online. any help on explaining where this wire goes will be appreciated, thanks. I have attached a photo of the wire and connector in question.
