I apologise if this has been gone over but I'm currently looking into swapping my F23A1 for a JDM F23A after a little incident involving a large puddle, no fender liner and no intake baffle. After some googlefu it looks like I'll have to swap over my current intake and exhaust manifolds as well...
Another thing you might want to check is the battery itself. If you have a helper have him hold a volt meter across the battery. Should read around 12 volts maybe a little higher. Then try to start the car and see if the voltage drops while it's under load.
If the voltage doesn't drop then I...
1998 Accord: tentatively sold it.
2002 Accord: tried to make a $5 short shifter which works great for about 5-10 miles before coming loose. And nobody likes a loose shifter.
My green Accord is getting sold here pretty soon (most likely) and I took a photo of both my Accords the morning after I bought the black car, so I decided to take a final photo of them both together before the green one is gone. Check out the link in my sig if you want to see what all I've done...
Thanks. I'm hoping to get my 98 accord sold here soon (the car on the right in the first post). Once that's gone I should have some money to put into the 02 and get it working better.
Putting a load on the engine doesn't make it stop idling. As long as your not pushing on the gas it's idling. (Assuming the car is stationary anyways) I would let it warm up and have it in park then turn on the AC and the rear defroster and see if the noise changes.
I had what sounds like a similar problem that ended up being the distributor. Here's a link to my old thread. I would give that a read and see if your problem sounds similar.

Does the noise change if you turn the steering wheel? And does it do it just in drive? I would try putting various loads on the engine like AC on/off, headlights on/off, rear defroster on/off etc. If it just does it in drive and not in park it sounds like it might have some sort of correlation...
While going fast can be fun I would recommend doing it at the track. There's just too much that could go wrong doing it on the road.
For example:
Someone could pull out in front of you and you wouldn't have time to react.
A deer could run out in front of you
Some other animal could run out...
I'm not sure if this is possible or not because i've never messed with the crank and TDC sensors but is it possible you plugged the wires into the wrong sensors?
