Hi all,

Just as I'm planning my trip to France my 2003 ML 270, it has begun to hesitate on part throttle. It only seems to occur on slight inclines when using part throttle around 60 to 70mph. It normally happens on cruise control but it happens without so not the CC playing up. It feels a bit like fuel starvation and the Rev counter needle rocks as the revs die and take up again, but only very slightly. Hope I've explained that clearly.

Apart from that it drives fine, and I can accelerate through this issue. Had a new MAF and injectors reseated.

Any ideas would be great or if you've suffered the same fault and found out what was wrong.

Thanks.
