OK, here's my problem. A few months ago, my car started running hot. I flushed my radiator, changed my 'stat, then I removed it, and checked my timing. It still runs hot even without my 'stat in. But here's what I don't understand. When going around town, it will stay relatively cool, around 160-190, but as soon as I get onto a freeway, 5 mins into the ride, maybe less, it would be at 200+. I thought normally driving at freeway speeds cool down the car quicker. Any help would be GREATLY appreaciated.

Sounds like you lost the air deflector. That's very typical for a broken dam. The airdam or deflector is the primary source of airflow to the radiator when speeds are in excess of 35 mph.

 

I agree, definately check the airdam and also check between your rad and AC condenser. Our cars have a tendancy to collect alot of debris in that area.
