Check Engine light code 10PCM PO128C?
Can anyone help me with this code? The code is not on a related thread that lists computer codes. Could stabile in the gas have anything to do with this code? I know the PCM refers to the power control module, where is it ? Thanks great web-site.

P0128 - Coolant Thermostat Below Thermostat Regulating Temperature

The "C" suffix indicates that this is a Current (versus Historical) code. Are you running a low temperature thermostat in a cold climate?

Not that I'm aware of. Light came on after car had been run for some period of time and everything appeared to be up to temp. Ran car longer and further on cooler days,without problem. I erased the code and will try car in the next week or so and if it comes on be more obserant of temps thanks for your reply. The only thing different since the last time I used the car was the addition of a smooth throttle body coupling to replace the original. There were no history codes. Do the history codes eventually disappear?
