Hey guys,
Bit of advice if you could.
I have a 2005 hilux, 2.5 d4d 2KD.
Under light throttle, just about maintaining speed it rattles really quite loudly.
The noise goes like a switch if you accelerate or let off.
Worse in colder weather and in warmer weather the noise quietens down a LOT.
Ive had a new fuel filter, new suction control valve and run some injector cleaner through.
Injector feedback values all good, well withing +/-3.
Done a reset and initialization of the EFI, Nothing made any change...
Its driving me mad!
I read a lot about a 'normal' EGR or Injector rattle but this seems very loud.
You can hear it over the radio but its only at that certain throttle position and a light engine load, starts/drives/stops fine otherwise.
Any suggestions?
Surely they havent all done this since new...
