120 prado D4D acceleration surge

[2toyos]

Few issues i face with the land cruiser 

Significant body rattle on low revs, been told its the frequency of the low revs, this has only just started for some unknown reason 

Rattle: 

Rattle only happends when driving, idling or rev no rattle

Acceleration surge

When Accelerating i will get a sudden surge of power, also kick down is sluggish, and feels alittle restricted overall performance

 

Any ideas, maybe transmission??

Hi Bud

After reading your post I would like to mention that I had the same problem and when I replaced my Injectors it improved dramatically, I did originally replace the nozzles as they are much cheaper than it is to replace the whole injector, however, in the end I found a company in China that makes injectors and they provided me with 4 which was around £900 cheaper.  Perhaps this is something to consider, how many miles has your car done?  Do you regularly carry out a service?  Sometimes the fuel filter can be a problem.  Do you have a DPF?  Regards  Mark

Sorry for the late reply mate, i had the injectors replaced and the problems have started, the engine was quiet and smooth, part from a misfire when cold, now all these problems with new injectors, im having arguments with the mechanics, i feel they have ruined my car, horrid low rev noise and vibration, misfires, blue smoke on fire up, Acceleration surge when kick down hits 3000revs, the engine isnt right, no i have a EGR system, its done 126000, since ive had it ive done all services on time, looking to do my transmission this year
