Thread: TD5 power problem

Blocked injectors or an ECU problem I would expect if it isn;t filters. that or perhaps a fuel pump on the way out (lack of power from lack of fuel) ??

Thanks Phoenix. If it was blocked injectors wouldn't it be a constant problem, rather than just when going up hills?

Your ECU suggestion has me worried.

If you know of anyone else with a TD5 Defender try swapping the air flow sensor, if this fixes it then that is the problem. It fits just after the air filter box, a very easy job.
This is a very similar to the S2 Disco V8 when the air flow sensor dies.

check that the big fat hose from the turbo to the air cleaner hasnt come
loose. they have a habit of falling off. only a hoseclamp holding them on but not much of a lip for the hose and clamp to grab onto.

Only on hills.... :? Problem is probably magnified on hills hence more noticable perhaps ?

So if you're going up the hill normally you floor it ?

Plastic intake pipes on that thing too ?

If that's the case the turbo would be like a hoover vacuum on 'roids and very hot. Used to be a problem on early performance cars where the turbo would get so hot, the radiating heat would soften plastics in the engine bay and some caught fire.

What might be happening is the plastic intake pipe is softening and with the amount of suction from the turbo is causing it to colapse, kinking off air flow. Next time you plant the welly into it up 'that' hill, check for excessive plume of smoke, could be starving of air.

If it has steel pipes the I'd still be suspecting heat. Intercooler efficiency?

Anyway that's my thoughts hope they help. [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

that was the other thiong I was trying to think of [img]style_emoticons/<#EMO_DIR#>/biggrin.gif[/img]

you can try mine if you like ... how far south are you?

I would be checking the hose fittings on the intercooler/turbo.If you are loosing the boost pressure thru a loose fitting,the lack of boost when its meant to be there would really confuse the electronic brainbox.
