Use the shbox.com site for your codes. http://shbox.com/1/Dtcs.htm
Or use the 94 F-car factory service manual.
DTC 43 is : Knock Sensor (KS) circuit
DTC 23 is : Intake Air Temperature (IAT) sensor circuit (signal voltage high, low temperature indicated)
Neither is likely anything to do with the pcm. Check the connectors of both. If ok, replace the sensors.
1998 Trans Am - LS1/A4 - all stock and almost all original - one owner - driven daily.
