09 nissan pathfinder 2.5 171bhp 120k

Had this car over a year, when bought it was in a very bad state and since I have changed or had changed for me the......

Blanked egr
Scv
Boost pressure sensor
Fuel filter & air filter
Nps
Vac line replacement
Full oil and filters change
Turbo solenoid

probably more that I've forgotten.
As I've never know how it should drive personally I still dont feel it's quite right ....

Takes a long time to rev up (from idle foot flat takes around 3/4 seconds to red line) no smoke when driving but does feel held back, once moving car drives quite well but the main problem I'm trying to describe is to do with pulling away from stationary quite often feels as if it wants to stall and when it does I have to pull away slipping the clutch, if I stop on a hill the clutch will hold me from rolling back but unable to accelerate away from this position without dipping the clutch and revving it up while the clutch is disengaged.

Also to add has never been great on fuel recently done a trip motorway driving 300miles cruise set at GPS 70mph on dash 76/77mph mpg was no greater then 26.4?? Is this also normal ??

Hope this makes sense to someone or they can shed light on the situation.

I refuse to pay for a dealer to look at it and I'm reluctant to want to send it to a specialist so I'd rather change what I can myself to try and fix the fault.

Thank you

I've moved your post to the Pathfinder section.

Definitely something not right.

It's the MAF nice and clean?
Any air leaks in the induction pipework?
Have you got an OBD dongle to look at the live numbers when the engine is running?

As above, it is well worth spending a few pounds (~20-30ish) on an OBD reader so that you can check your fuel pressures/mass air flow etc. It will save you a lot of time and money changing 'suspect' components by guessing.

Morning guys thank you and yes I have cleaned maf sensor multiple times and also have an obd reader using torque pro.
But as stated above I've never know how it should run so dont really know what the numbers SHOULD look like.

Thanks

Also as far as I'm aware there are no air leaks inlet or throughout the intercooler pipewor.

Good point.

It would be worth posting up the following so others can compare:

MAF readings at idle and light and full throttle.
Boost readings at the same intervals

I would also suggest checking that sensors are reading more or less correctly, for example temperatures and throttle position.
