First... I have not finished diagnosing this, but wanted to put it out
there.  I got back from the beach on Sat and ran the van through an
under-carriage rinse yesterday.  Immediately noticed a loss of power, about
40-50%.  If i put it in low(auto) then I eventually get it to run better,
but as soon as I switch to a higher gear, seems I lose it again.  Left it
overnite and took it on a 5-6 miles hwy drive to 'dry it out' but still same
prob.  Before I pull plugs and replace(also cap and rotor) I wanted to ask
advice.  Possible water in tail pipe? Also noticed temp gauge doesn't read
middle like usual. This happened right after rinse.  I had previously
detailed engine last week and all good to beach and back.  TIA
