98 Seville SLS Engine Codes

[mzepp4]

I just got a 98 Cadillac SLS. So today I hooked up a diagnostic test, the hand held one and 5 codes came up when I hooked it up to the Cadillac.

P0113 IAT Sensor 1 circuit High Input
P0440 EVAP Emission Control System Malfunction
P0741 Torque Converter CKT Performance or Stuck Off
P1258 Manufacture Control Fuel Air Metering
P0300 Random/Multiple Cylinder Misfire Detected

I'm working on the misfire, but i have no idea what the other ones mean.

Was the CEL on or are these history codes?
