It is on the Driver side of engine in between the COP's (Coil on plugs) simply unplug the wire use a 19 or 3/4 deep well socket and unscrew it and put it new one... The whole process should only take 10-15 minutes.

you probably have a vacuum leak. check all your hoses pcv hose for sure. it means the engine is seeing too much air with the fuel.

These cars are famous for leaky seals where the valve cover interfaces with the cylinder head, at the spark plug journals. They fill with oil, short the coils and cause a misfire. Driving it any significant distance can destroy your catalytic converters ad unburnt fuel ignites therein, creating inferno-like conditions and a fire hazard too. You'll get a "300 code", such as 301 if cylinder 1 is misfiring, 302 for # 2, etc. Pull the coil off the spark plug for that cylinder and if it is moist at all, that's your issue. Have new seals put in, or you'll just keep blowing coils at $50 a whack.

When the car is completely cool,check the electric fan(s) for smooth rotation.
Clean/check/change the thermo sensor,contact and wire.
Excavate air pocket in coolant system / check for head gasket leak
This test will kill two birds with one stone.
MAKE SURE THE COOLANT SYSTEM and ENGINE IS COLD!
RAN THIS TEST IN A WELL VENTILATED AREA ONLY!
You will spill some coolant during this air pocket purge test.......BE KIND TO THE ENVIRONMENT and ANIMAL please clean up after the test!
Put the front end on a pair of ramp or park your car on a VERY STEEP HILL (radiator facing top of the hill) .
Top of the coolant reserve tank
Let it ran for 10-15 minutes.
Monitor for air pockets escaping from coolant reserve tank.
Small amount of bubbles is OK at 1-5 minute mark
After the thermostat open up (after 195 F warm up) at
5-12 minute mark or after high idle you should see less bubbles.
If you do not see any in rush of bubbles then your thermostat may be partially stuck or rusted badly inside the thermostat hosing.
Give the thermostat host few gentle taps.
If you see larger bubbles surfacing after 15 minutes then should do a hydrocarbon (HC) dye test to test for potential head gasket leak.
Let engine cold down and top off coolant reserve tank.
Start monitor for coolant lost
A coolant flush is require every 2 years or 24,000 miles.
I recommend the thermostat that has a relief pop-let to reduce the change of burst radiator and coolant hoses.
Make sure you get a new thermostat gasket,black RTV and fresh coolant for the job.
