*ts- i own a 2008 dmax. i had that too 2 weeks ago. what i did was drain the fuel from the water seperator valve at the hood. did it a few times.

everything is fine now.

by the way. another symptom. if in the morning you start your engine and you hear a clatter in the engine before it runs fine in warmup then there is air in your fuel system. and so bleeding it is what made my dmax run fine.

hope this helps.
