No, sorry, I'll try a better explanation.
When you remove the manifold chamber (black plastic moulding) and look at the right hand bank (at the rear of the engine compartment) you should see an earth cable attached under one of the cam cover screws on the far right hand side (close to the battery). Make sure that it is present. It's illustrated in Haynes, page 2B-6, fig. 4.15.

As I said, I discovered from experience that it's possible to think that you have refitted the manifold chamber correctly when it fact it is improperly seated. Those two 8mm AF screws are there for a reason, to secure fully the manifold chamber which must be air tight. Attention to detail like this is the secret of long term reliability.
