Hi,
Anybody out there had experience lost of power. What is happening is that the engine does not stall but it loses power, when I press the accelerator it blows black smoke. It has happened to me 3 times, the first time I changed the fuel filter and also replaced the fuel bleeder that it was loose/damaged. Then it happened to me again on the F3, it fixes itself when I turn the engine off and then back on.
It seems to be a fuel blockage, but the fact that it does not stall and it has a new fuel filter.
Any help will be appreciated.
Thanks

Hi,
Had a similar problem on a HJ47 years ago turned out to be a blockage in the tank breather.
I'm guessing it is a HJ61 not FJ62 ??
The FJ62's were petrol ,if it has had an engine change it could be the petrol tank breather system not compable with the diesel engine.
Sorry I can't be more helpful.
Regards,
Joe.

Hi

Could also be an air intake restriction, like an intake hose sucks flat (may not ve visible from the outside due to delamination). That would explain why it comes good after stoppping as it looses its vacuum, and doesn't reapear until worked hard/temp high enough to soften the rubber???

Cheers Andrew

You may be right, I noticed that the air hose from the filter to the turbo is cracked. Not sure if that will stop the air from flowing.

Pelesino,
Not something as simple as a blocked air filter is it? If the fuel side of things is OK sounds like you given that some attention check the intake side as mentioned in the last reply.
Keep the shiny side up

Hi,
Air filter was replaced not long ago. But as I mentioned before the air hose from the filter to the turbo is cracked. Will that be causing the problem. ?

choke valve on inlet manifold electrical fault. turning it off and on again re-applies power

Squizzy,
Thanks for your reply, what you are saying is making sense. But what should I look for ?
The air hose from the filter to the turbo is cracked, can this cause the loss of power ?
Thanks,

If that hose is cracked that shouldn't cause the power problem you are having now but it will let unfiltered air into the cylinders which will dust the engine. you should replace that hose straight away.
If you have not fixed the problem post again after Easter as there will be a lot of people away and not online.
