Thank you so much Bill.
Well then I know its definitley not the P1811,0742 or 1629 as the car has none of those symptoms at all. I took it out today and it didn't seem like it was warming up like it normally woul or get to the temp it normally would. As well, i do seem to use more fuel then normal. Gonna take it out for a farther drive to see and really get a good read on the temp but by what you say, I'm gonna bet its the thermostat.
