So what would you suggest replacing? the TPS and CTS?sounds like it is running rich. when you step on the throttle, the tps tells the pcm to change the fuel ratio to richen the mixture. when the engine is first started the pcm is in open loop and it adjust fuel mixture by recieving signals from certain sensors, maf, cts etc. when the engine gets to operating temperature it goes into closed loop and adjust air /fuel ratio according to what the o2 tells it. the accelerator is just a valve for air and fuel to go through. it should be called air pedal cause that is what it is. the coolant temp sensor tells the pcm to richen the mixture in closed loop or when the engine is cold. it will lean out when it warms up.
