The light throttle rattle is not an injector issue. I had both light throttle rattle and cold engine injector knock. Replacing the injectors removed the cold engine knock but made no difference to the light throttle rattle that occurs at all engine temperatures, especially when warm. I took it back and complained as I believed new injectors would fix both problems. The inlet manifold and EGR were removed and cleaned along with the sensors, injectors checked and in spec….no difference! Wallet $4000 lighter. Still have the rattles
I've just done 12,500k in 8 weeks and tried to cruise between 90 and 100kmh to get good fuel economy. The light throttle rattles almost drove me insane. In every gear in the bush you get the rattle when easing on and off the the pedal for bumps ,corners etc . You could play tunes with the rattle on the OTL
First step is to find what the rattle actually is. I have seen a single reference to swirl control valves but that was all. Sammysau has disconnected his EGR and the rattle was still there so that says to me that the noise is coming from somewhere else. Anyone actually know what it is?
