2000 honda stops

[natureguy]

I washed the engine compartment and after 2hrs I drove my 2000
honda van and it stopped running at 1/8 mile. It will start but just
sitting it will miss at 3000 rpm. And it is at the same rpm all the
time, then it will die. I would like to replace all the parts related
too this problem, just need to know what parts. Thank You!
This is a used van with 170,000 miles and had ran very well.
