I have an 04’ ML 350 that is stmbling on initial acceleration…badly…it will stumble (almost cut off) in reverse and forward.
The only thing that I have done so far is replace all 12 plugs and wires.
Interesting note…while replacing bank 2 plugs, I notice that one waws wet…
What do you think the problem is?
Thanks,
Turpin

One what was wet? Sparkplug? Wet with water, gasoline or oil? What part was wet (the tip in the engine or the part the top of the plug?
Auto or manual transmission? When was the last time the fuel filter and air filter replaced?
Any CEL’s?
