I have had my 1.8 freelander on gas analyzer and its reedings are just over required limit. The Vehicle has just had a full service and lamba sensor. the cat was replaced over a year ago. the guy stated this is a common prob with the freelander. Has anyone experienced same and how did they sort it. Many thanks

If it's just over, then I'd try plenty of Lucas injector cleaner & a good long blast, but you might need to have the injectors ultrasonically cleaned if it does't work. Also remember reading a long time ago that wear in the throttle body can cause emission problems & a good secondhand unit will cure but you'd need to research that more as I'm vague on the details.

The cheap cat that got it through the MOT last year has now given up,I bet the Co reading was about 0.5-6%.
I have put a cleaner in fuel tank and was going to read co level over weekend. I have a throttle body as it does stick now and again just over 1500 revs but ifyou blip throttle it drops.
even last year with the new cat on it was just under required readings on analyzer. al let you know how it goes thanks

Yes - because the cheap cat was just that - cheap.The 1.8 K series exhaust gases need alot of finishing via the cat,most of the aftermarket cats have too small a monolith to do the job properly.Look at the size of the "brick" inside a genuine one and you will see what I mean.

I think yr right as when the cat was replaced by a land rover specialist they got the cat from a motor factor and it was £104 . Just priced a one up elsewhere( another specialist) at £240 Thanks for logical reply

If you know the MOT guy, ask him to rev the engine to around 4500 - 5500 and it will most likely pass, the 1.8 we used to have (before it got rear ended on our own drive by some fekwit trying to turn around on the narrow street - unfortunately it got written off) was way over the limit until the guy rev'ed the balls off it and it passed with ease, the only advisory was that one of the read diff mountings was shot and allowing the propshaft to hit the floor.
