I changed my thermostat last week and the replacement went well. Anyways the truck started up fine and then died after about 30 seconds and then wouldnt start back up for about a half an hour. Well it finally started and has been running really well with the exceptions of getting worse gas mileage than before the thermostat replacement and that when I use my remote start the Truck only heats up to about 150 degrees on the gauge until i begin driving and then within a short distance it is at 210+. I assume that the gas mileage issue is related to it not heating up I just dont know what is causing it to not heat up fully.

Thanks in Advance
