Start with a good tune up, new spark plugs and wires may do the trick, next check your fuel pressure, it should be between 41 and 47 psi, if it is too high look for dents in the line, also make sure your fuel filter is new.
A clean air filter is a must.
Check your PCV valve to be sure it is functioning, also the EGR.
Finally you can replace the O2 sensors, they tell the computer whether the engine is running lean or rich and adjust the fuel mix accordingly, if they are bad you will get a poor running automobile.

Where can you buy a 180 degree thermostat to fit a 4.2 liter 2003 Chevrolet Trailblazer?
That is NOT a good idea and I will try to explain why. The computer has to see 195 degrees to get the proper air to fuel ratio. If it is running cooler the computer sees that and keeps the mixture Rich. While running rich you are paying $4.00 a gallon for gas. If the cooling system is the problem THEN fix it.
How would being rich be a problem?
