Neg battery off! -when removing fuel rail be carefull not to damage nozzles -remove idle air control valve and hoses around -remove intake manifold (one bolt underside and oil dip stick holder) and you are there -notice the orientation of the sensors and wiring route btw, I have 2x850-94 w 500kkm ond and never problems with knocking sensors so it might also be the wiring or bad connectors causing the problems bt Tapsa Mark this post as an answer to my question<- Use this feature to mark quality replies to your post.
