Reallly weird check engine code

[GTBabyGirl]

ive never heard of the code i got.

running engine temperture below normal levels

is that a bad thing? the guys at advanced auto never heard of it and laughed that that was a good thing. i was kicking that code before i got my new hood, even in the summer. should i just get a lower thermostat? i know i dont need it, i dont have the mods for it, but would that make the code stop kicking? thanks!

What code is it P0125?

[GTBabyGirl]

no. it was simply engine temputer below normal running temperature

[GTBabyGirl]

it didnt say anything about coolant

[Ibwrong]

My guess would be the Thermostat is bad..

[GTBabyGirl]

thats what i thought. should i get the one that reads 160? or just stick to the 180?

[Ibwrong]

I'd stick with the 180.
