If you unhooked battery it will need to relearn its idle position, should help if you clean throttle blade edge and body of carbon so proper amount of idle air can enter engine.

Common problem on the 03-06 Trailblazer instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out.

You didn't mention what size engine you had. I am going to go with the most common engine and that would be the 4.2 liter engine. If this is your engine then the location of the thermostat is in the housing that the lower radiator hose connects to the engine. Just follow the lower hose and you will find the housing. Now you can't just buy a thermostat for it. The thing comes as a whole assembly housing and all and you can find it at your local auto parts store for about 25 dollars. Below is a picture of its location for you. The bottom bolt is not a problem to get off. The top one is another story and you have to get at it with a wrench and turn it a little at a time because you don't have much room to turn it. A little pointer is to do the top one first. trust me on this. Also when putting the O-ring which is the gasket for it you will need to use a VERY little bit of RTV to help hold it in place on the new housing when installing because it will fall out. remember to only use a little bit, just enough to hold it in place. If you use to much RTV it will leak. I hope this helps and is the engine you have and good luck.
