well the GP is crapping codes ... the P0481 I've had since I bought the car and the P0171 is fairly new. Now I know the P0171 could be caused by the MAF sensor, in fact most likely is being cause by it being dirty or shot MAF, However the P0481 is the real cause for concern... Fan controller 2 fault... as with the warmer temps .... I got home today and the GTP was really hot (boiling Antifreeze hot) so at this point I really need to figure out what the hell is wrong with this thing... I drive 25-30 miles every day mostly highway but the short distance off highway is when she really heats up ... So far I've checked the Harness as much as I could, Checked AND replaced the Relays for the fan controllers, even changed out the Fans and STILL have this issue ..... If anyone has any incite PLEASE let me know ....
