From what I can tell the car is 100% stock other than a K&N drop-in air filter that came with the car. The wideband is not yet installed. When I get the car on a lift to change the O2 sensors I'll see if I can add a bung for the wideband sensor.

The only DTC set in the PCM was for low coolant temperature and that code didn't activate the SES light. I cleared that code the night I got the cable together, logged the next day. The "SYS" message I'm getting persists. Through the process of elimination it appears the "SYS" message is not due to the code set in the PCM, but in another module. This is frustrating as when I previously entered CCM diagnostic mode I found no codes. I'll try CCM diagnostic mode again and see if it still gives me "ERR" when it queries module 4 (PCM) or if it shows any other DTCs.
