My car sounds fine when I start it. But the check engine light and trac light are on. Switches From P and Rand D just fine. But when you try to accelerate the rpm won't hit 2,500 no matter how much I push the pedal. It doesn't jerk or make any unusual sounds.

Hi,

These codes are for your throttle position sensors. You may just need to replace the throttle body which has the sensors included. I attached the tests and procedure on how to do this.

Please let me know if you have questions.
