Lambda reading and Part No!

[gbtvr]

Hi, not sure if Lambda is issue, but had the Lambda output measured and one bank was 1.037 and the other 1.3.

I assume I have a duff sensor?

Does anyone know the NGK part number for this by any chance to I can get from local supplier tomorrow? (V8 one not the same)

New Leads, plugs, and coil pack. Fine on light throttle, but stutters in higher gears at low reves, so think over fueling by lambda with those above readings?


Cheers.

first thing to do is determine if the sensors are faulty .. if both sensors are giving the readings indicated above then you need to do more checking. second thing is the sp6 sensor is a special, theyre the LR sensor if you have a 3 wire version but they're chopped open and a ceramic insulator/spacer put inside. the std sensors can't cope with the heat unless modified.
