My car runs great when it is cool outside. But when it gets really hot outside or really humid and warm outside I have no power when I accelerate from a stop. No engine light on. And the temp of the car is normal. When it does this I have to really step on the gas to get it to move. Please help. I really like my car except for this problem.

Do a fuel pressure check to rule out the fuel pump/regulator-if okay inspect and test the throttle position and mass airflow sensors.

Thank you. I will check the fuel pump/regulator and the mass airflow sensor. I have already replace the throttle position sensor.
