Question ml 320 engine splutters on very hard kick down
Please can anybody help me, my ML 320 w164 is experiencing problems when i put the accelerator to the floor at slow speeds, it splutters almost cutting out until accelerator is released, example when overtaking or pulling out from a junction quickly etc. It runs perfectly well under normal driving conditions and accelerates on a kick down at speed , sometimes slightly slow to respond though, it just seems to be when the car is at a slow speed and as maximum revs are applied.
any answers greatly appreciated and does anyone know of any good independent mercedes specialist in south wales UK.

After Kleeman KD Box, I put Speedbooster to eliminate turbo leg and above problem.

As conclusion, I have to say - it is working (almost, as driving gas engine).

Also, be sure that you upgrade transmission and Engine CU to the latest version - it is very import before you invest money to any above gadget.
