Let me guess!!!!!

Its an auto,if so tell him to suk it up you wont fix the fuel consumption

[gqmudder91]

hate to say it but no it's a 6 speed manual

[UGOTNUFN]

Ok thats very unusual, normally its the autos that drink fuel we never here of people with manuals having economy issues, So i would suuggest its probably an injector problem, its quite common,

[BundyRumandCoke]

Check the air intake system, sounds like too much fuel/not enough air in the mixture. Check for really rediculous things. I have seen a cleaning rag stuck in an intake, inside the air filter, which was the cause of some really crap economy.

[gqmudder91]

thanks guys will tell him but is there anymore ideas on both problems

[BadMav]

What is the power like? Clogged air intake does sound like his problem, but if the power is good, I'd be getting Nissan to check out ALL the sensors. I don't think the fuel can be just wound up or wound back on the newer stuff. Sure would make it easy tho.

he ius at work atm will ask when i see him next but from memory he said that it has stuff all power from takeoff unti;l bout 1500 revs when the turbo kicks in maybe bit more revs not sure will ask him but

I think you mite have same problem as my friends d40, its a injector problem, might need a new injector rail for it. should come under warranty.

while highly likly to be injectors, change the fuel filter first and most importantly reset the ECU.

lol they all blow black smoke my 2010 blew heaps from factory... maybe bad fuel too? mine has a crap tank in and used 17l p 100 towing today wasnt too heavy a load either

[gqmudder91]

wow thats crap thanks for your reply guys will let u now what happens

[rustygq]

hi guys, we have a d40 at work that had similar symtoms. it ended up being a broken timing gear teeth, skipped teeth, ( i think ecu tried to adjust fuel mixture to suit the timing after teeth skipped) and ended up needing new injectors at the same time. nissan dealer said it was becoming a more and more common problem. definately get it checked by dealer
