I have a OBD code PO125 Clsd Loop Fuel Ctrl insufficient Coolant temp. What do I need to look at for a fix.
HelloCustomer That indicates the coolant isn't reaching operating temperature.First make sure the coolant level is correct, if low fill the system, clear the code and recheck . If it's full I would replace the thermostat.That is the most common cause of that code.Jerry

The fluid was full, but was rusty so I am going to change it today, and try that before replacing the thermostat
I would replace the thermostat when changing the anti freeze.Jerry
