Landcruiser D4D down in power

[Lillywhite Timber]

Hi , im just posting this one in the hope someone has an idea whats going on . I very recently bought a SWB 05 landcruiser D4D . Shes a nice jeep etc but even on the test drive i felt she was down in power . 

I bought her aware of that and at a price that reflects it . However ! , i only had reason to put the trailer behind her for the first time the other day and now i see just how lacking she is . She hardly pulls the 12 FT ifor empty in 6th gear on the Motorway !!!.

As i say shes clean , miles are low genuine 110K , shes not noisy on start up . No over heating like the last one i had (which would pull a house down) , new rad solved it eventually .

Ive always got great pointers on here , far better than i ever gave unfortunately .

Over to you Guys

I had a D4D Dyna that had similar symptoms - turned out to be a very dirty sensor within the air intake pipework (possibly the air mass sensor). Took it off, gave it a good clean, sorted the issue! Had to subsequently sort the air filter housing that was letting dirty air through...

Injectors might need a birthday ...possibly

Fairly sure those 3.0 d4d have valves in back end of fuel pump, suction control valves, they operate with fuel delivery and pressure build up/release, switching from low pressure to high pressure when accelerating/decelerating. They can give bother, usually raise their heads at 90k - 100k miles, plugging diagnostics on should show sumthing with live data, and a ‘P’ code/number. Can change em, theyre usually a barsteward though cos often very snug to get at, and success rate is not always 100% though as they can wear the pump itself.
Best getting it plugged on for an indication.

I'd buy a cheap bluetooth diagnostics tool for sure. Check yer fuel and air filter.

Any smoke?
