At least a $12 pressure sensor got rid of the oil warning light which is a known issue on these vans.
The sparkplugs are relatively easy. The trick is to remove the wiper module, something like 4 bolts. You will need a new gasket for the upper intake manifold plenum. You will have to remove the injectors, they can be removed as a unit, it's easier then it looks. While it's apart, check the valve cover gaskets, odds are they are leaking, all the previous removes are needed for the VC's. Gaskets are expensive but will have to be done sooner or later. Might as well do them now.
Good luck.
Am I reading this right? You're advising to remove the upper intake and the injectors to replace the spark plugs? If so, that's totally unnecessary. I will say that it makes it easier, especially if you didn't eat your Wheaties as the angles that you sometimes have to work at can put you at a leverage disadvantage. But still not needed to remove the rear three plugs.
