Avensis 2004 D4D 85Kw Engine Problem

[Avensis Diesel]

Toyota 2003 Car of 85kW 2.0 D4D diesel.

Who have a similar experience with some of these engines.

The problem is this: if the engine is warm and then lowering the engine speed, the car starts to twitch. The car starts to lose power. When holding the accelerator pedal at the bottom, nothing happens. Motor is thinking for 5-10 seconds, then throws a cloud of black smoke from the silencer.

When the engine is cold, there is no problem. Cold start, idle, and acceleration is very good with a cold engine. When the engine reaches the normal operating temperature, the problem reveals.

Then again, sometimes I can drive for a long distance with a warm engine, without that problem.

Toyota service said that the problem is the engine nozzels. I switched off all four nozzles, which were very expensive. But the problem is still the same after that. So the nozzles were not causing this problem.

Waiting for detailed advice.

hello mate

check with the following: MAF sensor; EGR valve; SCVs (both); fuel filter element.
