how many miles are on your '02? I have an '02 Intrepid as well, 2.7 though, and when it's idling w/ the A/C on 90+ degrees outside, the temp gauge stays about halfway, I've checked w/ my DRB III I have at my dealership and that's ok. Do you have a check engine light on? The temp. gauge in your car is controlled by the coolant temp. sensor. The reason why I ask if you check engine light is on is b/c if you have a bad temp sensor, the light will come on. When it overheats, does the water boil and steam comes from your hood? One last thing to check, while it's running, (this is a little tricky so be careful) feel the upper radiator hose and the lower radiator hose, on the driver's side front of the engine. If the lower hose is cooler than the upper hose, you have either a bad thermostat or possibly a plug somewhere in the radiator.
