I have a 93 Cougar XR7 5.0 My car runs at 2000 rpms in park I just put in a brand new Throttle Position Sensor because i took my car down to get a diagnostic test done and the codes were shooting out that problem.... My car is still running that high what else would be wrong?

Check your Mass Air Flow Sensor, it is known for causing this problem as well. Take it off, and be VERY careful, but swab it lightly with a q-tip. The slightest amount of dust / dirt can reak havok on a motor (I know from experience). Try this and see if it makes any difference.
