changed starter and plugs .

To do that I removed upper radiator hose and distributor .. Replaced all of that .. In the process of getting last bolt off starter realized that oil pressure sensor had been snapped in half .. took it out looked for replacement .. for got to replace it before starting engine . ( good way to drain engine oil)...


But after getting all that replaced .. Engine idles at about 2700 in park ...

What do I need to look for first

 

The oil pressure switch is on the back of the engine block way above the oil filter. Is that the piece that you broke?

 

yes but that is fixed ..

the 2700 rpm Idile is the issue

 

Be sure all/any hoses are hooked up.

Does the idle drop once the car is warm?

Also, since you opened up the coolant system - you should bleed the air out of it. Honda's do not like air in the coolant system.
