Could a Lambda cause missing ?
Hi,
My limited knowledge of lambda sensors means i may be wrong in my assumptions, but is the lambda only used when on idle and cruising speeds? not on boost?
I have replaced my HT leads and Lambda today as i had a slightly lumpy idle, however this caused a bad misfire which occured anywhere between 2000 and well into the boost zone. I have put the old HT leads back and original Lambda back and its still doing it! so it looks like a coinsidence which is a bit odd!
I replaced the plugs a few months ago.
What do you you think would cause this?
I am getting no errors on the ecu.

I had a good look round tonight and can see the intake hose is badly mauled at the point it connects to the turbo. Someone has bodged it in the past with 2 jubalee clips but it looks like its not sealing at all. i moved the intake pipe a bit when I reattached the air box so this probably agrevated the situation!
