Problem with 4wd or low power on Nissan Pathfinder 2006

[Ronald]

Hi All,

 

I have a Nissan Pathfinder 2006. I took it to the dealer shop because we got a recent problem in which it loses power (and turns on the 4wd indicator) when it is in automatics gear, if I moved it to manual mode it works great. The shop tell us that the problem is happening because the injection pump is faulty.

I asked them why it happens only in automatic and they are telling me that Automatic mode is more demanding for the engine than the manual mode.  They guy didn't sound very confident so I want to get more info or recommendations on this. Has this ever happened to you?
