what jamobo said, mine runs much better having replaced it with a new one.

If theres meant to be a lambda on the ecu I'd definately put one in there imho.

i fried mine racing a golf gti.


I now have a new one and my car runs so much better.

ive just got a lambda sensor to cure my flat spot when i pull away................actuallay! will this cure my problem?? any advise ??

Think you can tap into the loom somehow and fit a resistor in where the lambda sensor should be, then your car will think that it has a working lambda sensor :)

My 20XE doesn't have a lambda sensor, and there is no where on the loom to plug one it...

aaah sweet dude, was getting a bit worried that if i push the car it will start to run lean. but at the moment it is almost undrivable, keeps wanting to stall when pulling away.

will post up on mig and see what they say.

mist, i got a feeling you can bridge two pins in the ecu or earth one pin to make it think there is no lambda.

mig will probably be more usefull though

yeah we are talking vaux, have a 89 engine i believe (20XEJ) but a cav GSI loom ecu and manifold, was running fine but now if i rev it hard ie hard acceleration etc the ecu light comes on, did a flash test at pvs and was came up with

13 Oxygen sensor No change in voltage/open circuit

44 Oxygen sensor Air/fuel mixture too lean (weak)

was reading on topbuzz that OS's are for cars with fuel injection and a CAT.

baffled

You dont normally have one without a cat i dont think. should thow up a fault code if were talking Vauxhall

Are these needed on a pre cat car? and if one is faulty how can it be checked?
