My hhr 2006 i try to clean the throttle body but now the relenti is to high how i reprogram the throttle body


You need to use the Tech II scan tool from GM to perform this relearn process. You can try disconnecting the battery for 30 minutes, but you more than likely will need the relearn procedure done at your local dealer.

How do I do a throttle body replacement relearn on a 04 isuzu ascender


The relearn is done by unhooking the battery for 30-60 minutes. With all HVAC OFF, hook the battery back up and drive your Ascender around for about 40 min or so, at this time, it will relearn. To test it, stop the vehicle put it in park and turn your AC on, if your car doesn't show signs of boggin down or trying to die on you, your relearn was done correctly. This is all assuming that your throttle body is CLEAN!!! If it's not clean, your idle will be bad and engine will try and die on you at idle when your AC or Defroster are on. Relearn should of already been done---> you always disconnect the battery when cleaning the throttle body, as to not to damage the stepper motor that moves the butterfly. To properly clean the throttle body and for best results, always remove the entire throttle body and clean BOTH sides with a sensor safe spray like Seafoam and a rag or nylon brush, you can reuse the hard plastic gasket. Hope this helps!

How do I adjust the throttle body


The throttle bodies on most newer cars are not adjustable for its idle speed. If the Check Engine Light is on, go to the nearest auto parts store and get them to pull the error codes from your car's computer. Post the codes back here and we can give you a better answer to your question
