Freelander 1.8 lack of power and acceleration

Alibro · Jul 3, 2019

Blocked exhaust (CAT) has already been mentioned as a possible cause so if the fuel pump doesn't fix it then that would be a sensible next step.
Also most K series have had at least one new head gasket so timing should be checked too. One tooth out is very common when the timing belt has been fitted incorrectly.

I have changed the fuel pump, but without success. I am looking at the cat now. The problem is that I can't remove the o2 sensor to see if there is any change in power. If I cat remove the o2 sensor I will lose the manifold screew.

Get a diagnostic reader on the car and see whether there are any fault codes retained. While fault codes often don't give a the direct answer, they do provide very helpful clues.
I agree with Alibro - timing is a likely culprit here. At the end of the day, the problem is either electrical (ignition) or fuel. Changing the fuel filter is cheap and easy - makes sense to do as part of a service. To be honest, I would always service an old car new to me. This offers an opportunity to change the cam belt and ensure that the cam timing is spot on.

The problem was the cat. I had put a second hand one with waranty and works fine. Also i have put the tester on it and before testing I had p0130 and p0135, o2 sensors. Now is all good. Thx for the help

Had the internal matrix broken up? Thanks for the update

If you refer to the interior of the cat, was just dirty from what i saw from one end... i don't know from the other side.

Yes, its difficult to tell from the other side without an endoscope!

Very sooty cats should be able to be brought back to life once the cat is up to temperature and the crud is burnt off. Generally this is done by driving it like you stole it: keep the rpm in the top half of the rev range in as low a gear as possible.
