Easiest way to read CO%?

[sealions518]

After referencing the throttle adjustment from the 2002 tii fuel injection pump manual it calls to read the CO% at the end and shows a picture of an CO reader. Is there a way I can do this without installing a afr gauge on my tii?

 

I am very new to these cars having only owning mine for a little over a year. I am however, excited to get my hands dirty!!

 

Best,

 

Josh

Meant to write CO instead of O2

Do you  mean a CO not O2 % reading?  Usually the CO  reading is between 2-4 %... if it is higher it means that the system is running rich ...if it is lower it means it is running lean.   One of the cheapest instruments to do that with is the Gunson analyzer unless you have access to  a professional unit.

You can use the Gunson's 'Colortune' if you are very cheap. Install in place of No1 spark plug. Use a mirror to see the colour, tune until you get a light blue flame. CO? No idea but will be ideal.

Ha ha after all that prepping this post I stupidly wrote O2 instead of CO :/ yes I mean CO.

I had one of those Gunson CO meters, back in the days of narrowband.  It worked.

Until I backed over it because I left it back by the tailpipe and forgot all about it.

 

But for the same money, a wideband tells you so much more, all the time.

Which, I suppose, isn't all that important unless you're planning on adjusting things.

To make things confusing...if you get a wideband, we are then talking about a wideband O2 sensor.  When I bought my CO analyzer 20 years ago it was the only affordable way to check if you were too lean or rich.  There was no such thing as a cost effective 02 wideband sensor.  Today, it  makes sense to get a wideband instead of the CO analyzer as Toby mentioned.
