Thanks for the replies.I dont think its a boost problem cause the van is even using much more fuel than usuall.I dont have a turbo light in my cluster.mine is the Jap import Ln112 model. The engine light does come up on full throttle but i dont think its a boost pressure problem cause i tried to take off the actuator pipe and blocked it so that turbo would be full pressure and when i hit gas down and the boost went up the engine fell in safe mode and was reducing power automatically but no engine check came on.So if it was the same boost problem the engine light had to come on when full boost but it does not.i changed the diesel filter too i tought maybe it was dirty or not original but no success as the fault is still there after i placed the new filter.i checked all the hoses but didnt find any type of leak but i am hearing a noise comming from near the exhaust manifold, i think the egr pipe is loosing some exhaust,can that make any difference?im sure its leaking a bit cause i can hear it very easy.One thing more is that my friend has a hilux like mine and on full throttle it changes gears at 3400rpm when mine changes at almost 4100rpm ,why?Im really going mad and dont understand why toyota changed to this type of engine!!everything is electronic! i prefer the old 2Lt with mechanical pump when you could just adjust the pump as you wish! might it be a diesel pump problem?? please help!!
