I just bought this car from an older couple who barely drove it. It has probably been driven less than 100 miles in the last two years.
I get an intermitent 'Service Stability System' message. It will go away for a time after the car has sat for awile, usually overnight.
The ABS and Stability System dash warning lights also come on. Any troubleshooting advise?

Scan your codes for me, off and warmer on the heater controls at the same time with your key in the on position, write them down and post them here

For the oil look in your owners manual for the procedure for the oil reset

PO113 is your intake air temp sensor, its stuck in your air filter box

your TCS codes are your light problems, my book says to ck your grounds to it or the BPMV pump motor is malifunctioning( high resistance in the motor ) or the ETCBM is bad
the first thing I would try is an etcbm go to the junk yard for this its expensive new, its the control module for the abs, the bpmv is the abs valve assy behind the module

the PZM code is a disconnected battery

IRC is source voltage low B1583, which is battery low
