Throttle position sensor might be bad

Or you could try to adjust your idle. But hey don't listen to me, you should go spen money and replace parts instead.

check for vacuum leaks... then iac, and fitv.

check coolant level if its irratic idling

i replaced the pcv valve, throttle position sensor, spark plugs, wires, distributor, throttle body, and its stil revving, tried to adjust the idle but the revv wouldnt come down, it was staying at a high revv, about 2,500-3,000 rpm. please help if u know what else could be wrong!!

maybe a vac leak

you can check for vac leake on your intake mani.......just use starting fluid lightly and spray your hoses and connections

to see what will happen when you have a leak, spray a quick shot into your intake and listen to what your motor does when it gets in there. This is safe and i know many people who check like this. It's cheap and easy.

take your intake off and let it idle open throttle body. there are 2 small holes in your throttle body, plug them with your fingers. if it stops then its the iacv. if thats the problem either block it off completely or try cleaning it. it wont hurt anything to block it off you just wont have a high cold idle anymore. its a very common problem for hondas.
