Mot Failure ... Lambda Issues

[Heph]

Just one stupid question, how can we clean spark plugs and is it of any use?

Thanks

Remove plugs from engine.

 

Check gap with feeler guage. Stif brush can be used to clean them.

 

See link below on plugs:-

Be careful when putting them back in, as it's easy to cross the thread.

Hi everybody,

 

I passed through the MOT test today with success

CO idle: 0.0

CO 2500 rpm: 0.0

Lambda: 0.99

 

So it was the faulty lambda sensor that was the cause... If anyone is interested, I got my new sensor from www.ntksensors.co.uk for arround 40£ / 60€ It was a universal NTK one so I had to solder it to the old sensor plug, but they also sell complete ones (BOSCH) at good price. They are also pretty fast...

 

I'm not in a hurry to do that jod again as it took me quiet some time... well next time I guess i'll be faster

As the manifold was out, I took some time to grind down the welding, it should flow better now.... might gain maybe 1 bhp

 

Thanks everybody for your advices and if anyone need some more details, just let me know....
