I have a 95 Bonneville SE and I keep getting codes for Manifold Air Temp Sensor and ESC Electronic Spark Control Failure. I noticed on the Passenger top side of Intake a sensor that was unplugged. The problem is that I can't find a plug or any wires that look like they go to it. Does anyone know where these wires should be? And, could that possibly be causing both codes. I THINK codes ar PO325 and PO112 or 121. Also motor jumps horribly when shifting out of park. I can only see one mount on pass. side and no "dogbone" type mount on top. Where are the other motor mounts? Please help, I am giving this car to my daughter in a week for her 16th birthday. Thanks!!!
