The car, after sitting for a few hours will start and idle for about ten minutes before it the rpms start going wild, it then drops to about 200 rpm and bucks in between 200 and 800 until the engine slowly stalls out. If i drive it it does the same thing if i step on the gas and try to get up and go. Its throwing out pcode P0449, which it has a new purge solenoid, new vent valve, new fuel pump and filter, and also has a new pcv valve.... Im at a loss on what could cause this. Any help would be great. Btw the car is aGTP so it is supercharged with the 3.8 V6
