i have a 2001 s10 and the service engine light came on and the code is p0128

I agree with wetry after you replace t stat and clear code if light comes back on run engine till you get to normal temp and then use a scanner to check the coolant temp you could a bad temp sensor

I agree with goodguy , replace, clear , VERIFY. And once it's fixed , sit and enjoy a bowl of green jelly. If we call farting 'breaking wind' then are the hurricane winds , God farting?

I AM GLAD WE ALL AGREE BUT THAT COULD BE A BAD SIGN! PS, I HOPE GOD DOESN'T GET GAS IF "SANDY" IS JUST A FART.

Scary how we think isn't it?

SCARY AS HELL!
