Hi
Can anyone tell me i have a few symptoms which i feel may be injectors
my 80series ONLY when hot idels rough and is sluggish usually after a long drive on the freeway and even on a hot day.

And only after a long trip the next morning when started it runs rough and blows a bit of smoke as soon as you rev it a couple of times it is fine

It sometimes also has heaps of power compared to the way it normally goes it feels like a petrol motor (this doesnt last long though it soon returns to normal)

Is this a typical 80series Diesel or does mine just have to be different ?

hi, i think it is typical for the 1HZ diesel motor to be like that.

I know it sounds like somthing is wrong but i have a 94 model landcruiser ute which has the same motor as yours and i have the same symptoms as you described.

My motor has done only 148 000kms and runs perfect otherwise.

If you are really concerned, get it checked out.

Symptoms of injector problems include lack of power, black smoke especially going uphill, poor fuel economy etc. I'd make sure the fuel system was A1 first. Injectors need looking at around every 100K.

The running rough after getting hot would suggest that something is expanding with heat and maybe letting more air into the system... ???

Just guessing.. but injectors are black smoke when revving up hills etc. Friend following you will soon tell you!!

Mine always runs with more power in the evenings. I think!

How long since a fuel filter change and a dose of chemtech conditioner?
Yes the old diesels do lose power when hot, never mind the additional power drains caused by a/con and alternator (running fan etc) also the engine cooling fan will be on much more robbing power as well.
I've always smiled to myself with the old truck on a cold wet foggy day really flies, all that dense, moist air, no cooling fan or a/c load all the grunt in the world and you have to watch it because of the slippery conditions.
