what is the TCC system?
meaning headlights? interior lights?
also, B1324 - A/C Refrigerant Overpressure. how would i go about adjusting that?
also, P1599 - Engine Stall or Near Stall Detected. This i know is just a detection, but i think it has something to do with my RPM sway that i mentioned before. my RPM's range from about 500-1100 when the car is idling. no codes have to do with the idle air control i'm thinking that possibly my faulty FPR may have something to do with this? possibly?
finally, U1064 - Loss of Communications with DIM. meaning...?
appreciate any help guys...
The TCC system is the Torque Converter Clutch system.

I would guess that it means headlamps... What one is giving you trouble?

Did you add freon? If not then I would suspect that a pressure sensor went bad. Either that or the orafice tube became clogged (you don't want it to be the orafice tube).

Yeah I would suspect either a vaccum leak to the FPR or a bad FPR for the idle issues.

Loss of communications with the DIM means that the data line is interupted or cut between the IPC (Instrament Panel Cluster) module and the DIM (Drivers Information Module). Check the plug connections.
