Hey guys not new to site but first post.I have an 07 Sonata v-6,that on a fresh cold morning start,or sometimes at the end of a work day,I will start the engine,the engine will start fine,the engine will idle rough after 20 seconds of running,then will throw an engine light up.I shut the car off,and restart the car,engine may do the same thing again,or it will let me drive a short distance then the gas pedal will die which will not allow the engine to rev or drive.I have replaced the pedal and sensor under dash,and tried cleaning the throttle body.Cleaning the throttle body seems to help for about a week.It seems to occur more on cold damp mornings or cold days.After the engine warms up ,the problem is gone.Thanks ahead.

 

Update: I got a good deal on a new throttle body,instaled it,and things are good now.Word is ,that you can just replace the TPS sensor to correct the problem my car had.
