failed mot on emissions

[Akenning]

Hi,
Had my mot today car failed on emissions, tester said it smelt Rich. Here are the results,
Fast idle test
Engine speed 2810 pass
Co 6.53 fail
Hc 350 fail
Lambda 0.827 fail
The cat is worn but doesn't seem to be blowing. Tester said there was a slight misfire at high revs. Plugged obd2 reader in no faults showing. The car only does 5 miles a day but had a 20 minute run before test. It has had a ktech induction kit fitted for 15th months and it hasnt been cleaned
. tester left it running for the whole test so it was warm for the emissions test.
Any help or advice would be great before I go throwing money at the car, again.
Thanks Alex.

Slip him some money and see if it will pass now?

If you have a slight misfire it might be worth checking/changing the plugs. You should also be able to tell from the colour of them what sort of condition the engine is in.

If the cat is knackered and you want to stay legal you will need a new or good secondhand one. The misfire may have been the cause of it dying.

New cat is on the list of things to do so it will be replaced soon. And the plugs where done about 3 months ago with the correct plugs. Last mot passed no problem.

That is way out im a tester myself try some plugs fuel up with some premium and injector cleaner and give it a thrashing a proper thrashing

I'll give it a go half hour on the motorway do it?? And am I aiming for high revs or just normal high speed driving?

A good Italian tune up will cure a lot of problems.

Why did you buy a 182?
Give it some high revs, throw it around, get that rev counter moving man!!

This is pre-cat lambda and happened to me in January - a basic fault reader won't see it.

I got the lambda changed and it passed with flying colours.

As above my lambda caused mine to fail, passed after changing it and a run.
