Ah, thank you both. Tried the scanner from Checker & it didn't work, needed a different adapter for the plugin. Autozone was successful with the stadard Actron reader in reading the codes (P1115 & P1275), but they said they wouldn't reset them for me.
I have some about clearing the soft-faults by disconnecting the neg. battery cable & that I may have to reset the radio if I do that & I do have the serial number if needed. Any suggestions or BKM (best known methods) on this?
Based on what I've found the errors are:
P1115 Oxygen Sensor Heating 1 After Catalytic Converter - Above Upper Limit
P1275 Aging of Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Below Lower Limit.
Will try to reset the CEL, if these come back, I guess I'll be replacing the O2 sensors...
I can only find gasoline with a 91 MON octane rating around here, could this be a root cause? Do I need to add some octane boost since it's reommended to be running 93 MON????
