low idle(750) CO1.70% above 0.5%fail
lambda0.919 between0.97and1.03
high idle(3050)CO2.89% above 0.3%fail

any help would be great engine is unmodified o2 sensor in manifold was plugged in thermosensor in cat was not

That is an unusual test. But CO is caused by poor combustion.

Can be anything that has to do with timing,
and fuel. Like a plugged injector or high fuel pressure, or even old gasoline can do it.

Check the O2 sensor also because it has to do with fuel ratio's

I have to ask...Thermosensor??? in the cat? Can't help you on this part because I have never heard of such a thing.

its looks like a o2 sensor but it plugs into the cat.
what would you do next if this was your car????

kenny7

ok i have no cel light on but i checked for a code and i got one flash this is o2 sensor right??

If it's one short quick flash, they yes, O2 sensor.

I'm still unsure of what this thermosensor is...or does. Can you explain more? Is it actually a sensor...or an air pump of some sort?

kenny7

it looks exactly like a o2sensor except its just a single wire .
