Re: 1991 Olds Ciera 3.3L Code 43
Welcome to AF !!
The 14 is Engine Coolant Temperature(ETC)Sensor Circuit-high temperature, I doubt that would keep it from running but wouldnt hurt to check the wires/circuit.
And the 43 is the Knock Sensor(KS) Circuit - spark control.
I would check that circuit it could have came unpluged , does sound like a bad KR though.
