Disco II Auto lack of Power

I just bought a 2001 Series II Disco Auto. When cold it has no power. For instance if parked on an incline it has no power to pull away. Even when you depress the accellerator fully it will stand still and the engine revolutions remain static. Problem goes away when heated up. Is this common or what could be the problem?

Sounds to me like it could be a compression problem. When you had your service did they lift off the heads?

No hand signals, driver playing with his transfer Knob.

No. If it is compression would it go away when hot, because she pulls fine otherwise

Are you saying that the RPM does not change? It stays at an idle?

That could be as simple as a throttle linkage problem. But I have no idea why it would change when it warms up ...

Is this a diesel? I've read something about later model diesels having a drive-by-wire throttle (or maybe I'm hallucinating again). Anyway, the rack in the inj. pump could be sticking.

Yes, it is a TD5. The rpm's increase to a point and then remains there without having enough power to make the Disco move.

Aha!

[QUOTE=DiscoPat]Yes, it is a TD5. QUOTE]

TD5 is cableless, 'fly -by-wire' throttle. You're going to need the dealer to hook up his computer, but I have to say, I think it is an ecu, or electrical problem.

Td5

Hello Mate,

Sounds like air flow or EGR fault, also there are position settings on the throttle. Can be done by an independant with decent equipment i run autologic and it is more than capable.

Or for more power you could chip it i fit Twisted Performance at 395+vat great for the model you drive.

Regards

Dave

Thanks for the advise. Before I can solve this problem antoher one has arised (which might be related to this problem). When trying to start in the morning the motor only turns slightly and then "locks" (as if the battery is flat). Sometimes it would start but come to an abrupt stop. After a few attempts it runs but emits a lot of black smoke. Once heated-up its fine. Somebody told me it could be the injectors, or just one, that is not cutting-off and dripping diesel into the cylinder. Do you think this is possible?

PS. I have also noted that it runs very uneven when starting up when hot, but this disappears after you rev it a couple of times.

blackdown 4x4

They do have injector seal problems, and also the injector loom in the head causes misfiring due to oil ingression. Without seeing it???
