i'm getting code 15: low temp indicated at coolent temp sensor, and code 23: low temperature at manifold air temp sensor or throttle position error. anyone have any ideas what i do about these? i just got this car, and the thermostat housing and the radiator were leaking , so i replaced both of those. i was going to just put the old thermostat back in, but the person i sent out to get all the parts came back with a new thermostat so i just put it in, the box says its a 195 degree. after i did all this the check engine light would come on after the engine got to around 120 degrees. i looked at the throttle body and theres a 2 prong connector that isnt plugged in, but i cant see where on earth it goes. its in the throttle body, coil, and destribitor area. i looked as best as i could but couldnt see any place for it to go. the car seems to run just fine even when the light comes on, i normally wouldnt even worry about lights, but this car isnt mine...its a female's that i just work on. and you know how females get when the engine light comes on.....
