Welcome to the forum. Sounds like it may be in limp mode.
What was the code # on your 2008 GP with the 3.8 ?
Are there any other associated codes, when using a good shop scanner?

Yes..1st off thank u for replying..I appreciate your time..The codes associated are P2138(throttle body) P2120(pedal position) P1125( manufacturer control) P0449( evap vent valve/ selenoid circuit)..All comes on wen car goes into limp mode REDUCED ENGINE POWER..I jus ordered the evap parts bcuz thats the only thing i didnt replace yet..Wut i hav repalced so far with all new parts is as follows- Throttle body, gas pedal w/ position sensor and 20 way connector harness with leads..I did an idle relearn procedure after puttin in the throttle body, gas pedal and new harness..Car drove for an hour then went back into Reduced Engine Power mode makin all the other hand in hand codes come back..Do u think i hav an electrical wiring issue or can it be from replacing everything except the EVAP VENT VALVE CANISTER and EVAP SELENOID ?
