I have a 93 civic hatchback with a d15b7 engine in it, there are 2 cables on the throttle body, 1 connecting to the gas (coming from the right hand side) and one coming from the right. IDK what the one on the right is, but whenever i have it connected my car will turn on and turn right back off after i rev it a couple times. Could someone tell me what this cable is for and how i fix this problem, the car will stay on when i dont have this connected

 

Post some pictures.
