i thought it was called throttle position sensor but i went to shop to get a new one, they said according to the part number i gave them it is called idle control unit.
i phoned to a second hand dealer and asked for idle control unit. she said there is none. then i asked for throttle position sensor. she said they have the whole throttle unit. it costs £45 plus vat.
what was she talking i did not get. what is the whole throttle unit?
