Thanks for choosing Just Answer . I'm Wolfgang here to help!!
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail. Do not rate yet, just reply. Put yourself in my shoes, I can not see, smell, hear, feel or touch your car, nor do I know any history on it. So take into consideration I am doing my best based on what you tell me. Also understand fixing cars often requires sophisticated tools, that you may not own. So even if you can not do what is outlined in my answer, that does not mean my answer is wrong deserving to be rated negative.

i do need more information..

  1. i do need the vin # ***** the vehicle
  2. any recent accidents ?
  3. any recent repair work excluding the throttle body?
  4. if you look at the coil wiring is the insulation cracked and wire exposed?

please let me know!!


Customer: replied 1 year ago.
Vin number is *****
Car was not in accede as far as I know
No wires exposed no cracking all tape is original however since the last post we have tried a different gas pedal that does work from same type vehicle just it was a 03 hope this helps it's mind boggling.

Expert:  Wolfgang replied 1 year ago.

Customer: replied 1 year ago.
Yep it says error when trying to adapt using channel 060 also shows 14.7%
Verses 87.5% keeps giving code for throttle valve electrical error.
