This built-in signal got your attention, didn't it?

Yes Jim it did. However, when the light comes back ON again, does this means the GPS are powered up again too?

Thanks

No, GPs have cycled normally but since a fault is sensed, the lamp comes on as a diagnostic message.

Thanks for your reply Jim,

I still have to do some testing to find out which one is dead.

The back GPs are imposible to get to ! I read that the inlet manifold has to be removed. if this is true, what is involved in do it that?

cheers

The plugs may not be impossible, but I hear that removing the intake manifold makes it a lot easier.
