Sensor question!!! HELP

[flames5351]

Ok does anyone know what the sensor is called that is located under the intake manifold. Right under the hard coolant lines that run accross the engine on that side. Its like right in the middle of the engine on that side. I accidentally ripped out the wires/plug somehow and was wondering what it was called so I can pick up another one. Or if it would be alright to run without it. Thanks guys

Oil pressure sensor or knock sensor? Knock sensor is bolted to the engine.

no its not the oil pressure sensor... I bet its the knock sensor... it is bolted to the engine. Hmm... wonder if its a bad idea to run without it. Or do you suggest replacing it?
