99 Honda prelude overheating: if I remove Prelude Thermostat would that fix my problem? I would replace it down the road. $$. When I step on the gas it starts "cooling down"

So if your driving it doesnt overheat only when you come to a stop?If so sounds like your radiator fan isnt working or turning on when it should.

For fuel injected vehicles the thermostat is a very important component that should never be removed. If you have an overheating issue, removing the thermostat is not going to solve the problem, most it can do is delay the overheating.

Saturntech9 is correct about the cooling fans not working, or you could have very low coolant in cooling system.

Would you suggest a quick fix by making a shortcut to be fan by hooking it up directly to the battery and making an on/off switch to the dash?

No that's a good way to cause a electrical fire the switch can't handle the load of the motor without a relay trigger point. Also is the car only overheating when your not moving?If so is the radiator fan on when its overheating?

Start by testing the fan motor to see if they works.

So do you know its overheating because the temp gauge reads too high or because coolant is boiling out of the radiator cap?

Have you checked the coolant level both in radiator and recovery tank?
Do you need to be replenishing the coolant very often?

Was anything done prior to this occurring?

You could have a bad radiator cap causing a coolant loss and then it overheats.
