yes customer changed a lot of parts with his mate
he said he baught the stepper motor from the ebay but it does't seem to be moving atall and there's a fault code in the ecu for it.there are
3 wires with battery voltage and 3 with earth in it's plug. the tps has 2 signals 1 with 0-4.30v and 2 with 640ms-4.92v the os is switching well
but the injector is paulsed at 2.2-3.1ms insdeed of 1.9 according to a.data so it's overfueling
so what do you thing could the dead stepper motor be causing the overfueling ?
