après quelques recherches, voici ce que j'ai trouvé :
"I was told by a dodge mechanic, that the only 2 ways to clean there throttle bodys is 1. use a scan tool to open throttle to wide open, or 2. have some one turn the ignition on but don't start engine then have then slowly push the throttle all the way wide open, then get in there with throttle body clearner and a tooth brush and get at it lol once done cleaning have the person who is holing the throttle wide open to slowly release the throttle. then turn off ignition. this is what he told me ......Yup. Don't touch it with the key off, or the battery disconnected, unless you want to buy a new one. You have to go Wide open throttle with a scan tool, or it MAY do it with the key on, foot down on the gas. The TPS and the Throttle actuator are both on the same shaft, so it may lose position if the key is off or battery disconnected. Take the intake elbow off, key on(not running), see if it opens wide. If it does, have somebody hold the pedal, get a tooth brush and a can of intake cleaner, get er done!!"
Je vais donc tenter d'appliquer la deuxième solution car il semblerait que toucher au papillion déprogramme sa position. Quelqu'un aurait-il déjà pratiquer cette solution? (Contact mis, gaz à fond) ?
