Q: Hi, my ML430 has started stalling while I am at lights. It has happened 5 times on 1999 Mercedes-Benz ML430

4 of the times it has re started straight away on first key turn but once it took several attemps.
Also I could be accelerating on a motor way and suddenly my accelorating power goes for 1 or 2 second and then returns.
There is nothing on the dash and it always starts first time, is full of fuel etc.
Just had a full service with filters and oil changes too.
This is not an easy fault to diagnose remotely.

I would measure the 12v from the battery into the fuse box and see where it goes, if you have a fine probe you can measure the voltage on the various fuses and see if you can isolate the problem to a cable (if you are lucky) or the AAM if you are not.
