corsa 1600/16v.
lambda - between 1.35 - 1.6
cO - 0.00 %
HC - 50ppm
FAIL.
any ideas as to the cause??..
when the lambda sensors unplugged, i get:
co .13%
Hc 73ppm
Lambda 1.01
Pass lol
the lambda sensors on the top of branch 3 of the 4-1 (if that helps)

If you get a lambda value of 1.35-1.6 with the lambda sensor plugged in then is most likely knakared, its the job of the lambda sensor to keep the lambda value at 1 when its idling and cruising

Not sure If having the lambda sensor in one of the pipes alone would make a difference though, someone else might be able to help you there

Take the lambda out and have it put in where it normally is on a standard manifold.
Where it is now its mis-reading.

faulty sensor imo
but, it is far better to weld in a boss so you can screw the sensor in where the 4 branches meet.

did a voltage test on the lambda today (disconnected)
got:
idle: 0.8-.9v
over 3k: 0.1-.9v (irratic as hell)
engine off: 0.3v
id say the sensors fooked?...anyone else have a view?..
BTW the sensors always been in this branch its been fine for nearly 3 years lol.

Fine as in "working" yeah.
Its not at all ideal though having it reading one cylinder.
What was the Co% with the lambda connected?
Does sound like a dodgy sensor.

with it connected it was 0%, the only reading out was the lambda (hc's were all over the place, buit mostly below 200ppm)
