low coolant temp fault code
I replaced the factory t-stat with a 160* t-stat, I didn't change anything else programer told me I wouldn't have to reprogram just for t-stat. but the check eng. light comes on with a coolant temp lower than factory preset code. called chevy dealership and talked to shop manager he said it should be doing this no reason to reprogram but I clear the code and it comes back on anywhere from 1 day to 4 weeks. any ideas????

the ecu is freaking out because the engine isn't warming up as far as it's concerned. the only way to fix it is to tune it out i believe. i don't think it'll hurt anything the way it is though.
