Thanks for the tips guys. Went to AutoZone and they read it right out for free...I was apprehensive to go at first, but I'm glad I did, I highly recommended it first a first-cut diagnosis.
Anyways, the fault code was "P0128". The description was, "Coolant Temperature below Thermostat Regulating Temperature." The service tech tells me, "you know someone was just in here and had the same code...that tells me it's too f'in cold out"...he says. He said it was okay and not to worry about it...what do you guys think?
As it turns out, once I started the car to leave Autozone, the SES light was cleared out. I wonder if maybe the guy reset it?
if the code is reading the coolant temp is below spec and the temp is remaining normal durring drive, the thermostat is probably sticking open and just letting the coolant circulate and not reach it's operating temp "in time"...something to check out.
