Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.
* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.
NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

Most thermostats are located in the upper radiator hose housing mounted to engine block. Make sure engine is cold put a catch pan under your car to catch any antifreeze that comes out. Remove the two bolts holding the housing on the engine and remove thermostat and gasket. Clean engine block where gasket goes very good and also the housing, have to remove all gasket material so when installing new one it will seal and wont cause a leak. Make sure when you put the thermostat back in it goes in spring side down towards engine. Replace housing and bolts. replace lost coolant with a 50/50 mixture in your recovery tank. Start engine let heat to temp and check for leaks.

I had a similar problem with my car. It turned out the O2 sensors were fine and the issue was a leak in the throttle body causing the engine to run lean. If you have an ODB2 scanner you can look at fuel trims, etc and will be able to tell.
