Did you buy the car new or used? Have you installed an aftermarket Fuel pump? ie.. Walbro FP? the code p0183 refers to the fuel temperature sensor "A" circuit high input. Did you retrace your steps to see if while installing your TBE you unplugged something? any other readings the AP is telling you besides the code? are you boosting properly? I am sure others will post their knowledge/findings as well. Good Luck and Welcome.
