Help Catalytic Question

I have imported my Jeep 95 4.0L to the UK
from Saudi Arabia. Just done the emmision test and it failed. It has no cat and failed on CO % VOL. Jeep runs great, but have to pass the test, so I have bought a High Performance Cat from Random Tecnology.
There is no sensor and is not required with this cat as I understand. When I fit this Cat is it going to pass. Lets hope so !

Results of CO % were as follows on failed test.
Fast Idle 1 (2500 RPM) Limit Mine
0.30 0.97
Fast Idle 2 " 0.30 1.24
Natural Idle 0.50 0.63

It passed on HC ppm VOL and Lambda.
Many thanks

Well, given your numbers and what is needed to pass, you should have no problem passing with the RT cat. Just make sure you drive about 20-25km right before your test to make sure the cat is heated up real good, has burned off any lingering petrol soot and is doing it's job. Good luck!
