Kim, if it had low oil pressure it would not be exhibiting the 2200
syndrome. It can idle all day, or drive as far as you want without
hitting 2200 rpm, and then when it does, BZZZZZZZ.

Yes I believe I did get them in the right place. I put the black one
behind the water pump and the grey one under the engine tin. If a wire
has come loose it will do the same thing. I had that happen on my 90.

I just changed oil today, used 20W50 of course.
