Remove it. Walk to the nearest trash bin, and drop it in. Pick up the nearest phone and call Hondata. That's a sure fire way to fix it.

Do you have it hooked up correctly?
Have you opened it to see if everything is inside? (washer, diaphram,spring, retainer)
Sounds like you have it hooked up backwards.

Although there could be a few more reasons...

Yes this sounds like what is going on. If your going to use a FMU, look into the cartech 2005 units. A very nice FMU, which is adjustable.
