Title: CO Emissions
Post by Nunnspoet on Oct 18th, 2017, 8:44am
As reported in "News," "The Beast" passed the MOT yesterday.  However I do have some concerns as the CO emissions are just about legal and I would like to remedy this.

So here I am once more looking for excellent advice from you chaps.  She has just recently had the loom re-wired etc.  2 New Cats fitted about a 10 days ago.  I cleared the fault codes: Both post Cat H02 Sensors - high voltage, and in "Enhanced" Bank 2 pre-Cat Sensor "Switches - Sensor indicates rich."  Having learned that the Electrician had not cleared the Fault Codes on my other Cossie I was/am waiting for some miles to pass before I check again.

In the meantime she drives absolutely superbly, can't fault her.

What do you think??

Mike. I think it is a close run thing with these cars now. I have exactly the same problem with my car each year. :(

Just found an old MOT certificate for my 2.3 16v Scorpio with 148000 miles from Dec 2010 - CO readings as follows :

Fast Idle : 0.03% - Limit 0.20%
Natural Idle : 0.08% - Limit 0.30%

If your MOT readings are very close to the legal limit you might have a failing sensor.

I would say, replace the lambda sensor.   Go for a decent one rather than a cheapo, I replaced my Jag ones, cost £135 for the two.
