2000 ML320
Anyone experience bucking/hesitation on acceleration when cold?
Hi guys I have a 2000 ML320 with 120K on it. So this morning I was headed to work and the ML just died while driving, all the gauges dropped and all the lights came on the instrument cluster much like when you initially start the ignition, then it picks up again and drives like nothing happened for a bit and does it again.... No warning lights staying on....
It did it about 5-6 times and seemed to go away once it was warm.... on the way home from work it did it once shortly after start up and then was fine after that....
I was thinking something electrical... but i'm about to run down and check if there are any pending codes....
Any help or ideas are much appreciated, I really need a reliable vehicle...
Thanks

update:
looked for codes nothing showed up... more detailed description of the problem...
It looses power on acceleration with an abrupt and rapid loss of power, when I lose power, the vehicle behaves as though I turned the key > dash lights turn on, and all the gauges drop a second later it picks up again and takes off like nothing happened, but this all seems to happen more so when it's cold, less so once it's warmed up and at a constant speed. This happened 6 times on my way to work this morning and once on my way back.
Recently I changed the fuel pump, fuel filter, and CPS, plugs all fluids and the 4 O2 sensors, since It's been running great till this started today...
Any help would be much appreciated!
Thanks
