Engine seems stuck between 2500-3000 RPM - Land Rovers Only

I have an automatic 2002 Freelander TD4.
I was on a trip this weekend and I noticed that when I was between 2500-3000 RPM in fourth gear the engine seems to stuck, it doesn't develop...

Even if I floored it on the gas pedal, it just didn't seem to develop.

One of two things would happen, after a few seconds, it would just jump from 3000 to 4500 RPM, or I had to manually go to 5th, speed it up a bit, and then reduce to 4th. Since when I reduced it went to 3200 RPM or something similar in 4th, it would develop normally, but as soon as it dropped to 3000, it would get stuck again.

I also noticed the diesel comsumption really jumped.

Normally I would go to a dealer and have it checked but in Angola you definitly can't trust this guys and I would prefer to go there with an ideia of what the problem is.

Any ideias?

My bet, after reading your post, is that the throttle cable has begun to fray, causing your 'sticking' problem. Examine the cable closely (at both ends) as sometimes it frays just before, or even, just inside the sheath it goes into.

There is no throttle cable in Diesel Freelanders - electrical inputs from the pedal to the ecu - electrical impulses from the ecu to injection system.

There is probably a faulty sensor somewhere telling the ECU to keep revs up - a diagnostic check by computer at a dealer is probably the best shot - I appreciate the issues associated with this.

I didn't know that. Thanks for the info.

Someone told me this could also be due to dirty air filters.
In Angola even in the city you get huge amounts of dust, so it is very likely that my air filters are in fact dirty.

I'll see when I can put the car in the shop and if that was the cause I will inform the you guys.
