davidreader5,
Have checked all measurements. All are ok and within said measurements.Thanks.
What happens if you disconnect lambda sensor while engine is running? The reason being is that i can see bare wires on the three that are attatched to the sensor. I have noticed that there is slight arcing from them.I have only noticed this now that i have removed heat sheild from turbo.Would this effect the running while the engine is idling? I did disconnect the sensor when i noticed it this evening and didn't here/or notice any difference in the running.

Dave Henshall,
I know what you are saying. It just makes you jerk about slightly and it get annoying sometimes.

Cheers

Graham.
