Well I got out the head today but accidently, while moving the harness out the way pulled on a sensor and pulled the wire out of it. I wanted to know what kind of sensor it is. Its some sensor underneath the intake manifold right next to the starter, its on the block. I know there is 2 one in the side front of the motor, and the other in the side back part, next to the starter, if anyone can tell me what kind of sensor it is that would be awsome, well thank everyone and have a nice day.

That sensor is the VSV for the EGR valve, or vacuum switching valve for the exhaust gas recirculation system. If you have your EGR blocked you should not need it and otherwise remove the vacuum lines that operate it. If you have a JDM engine you shouldn't need it as mine came blocked.

or could be a knock sensor.
how many wires go to the sensor? one or two? are there vacuum lines going to and from it?
