2003 crv imrc (imtv?)

My "Maint Req'd" light came on and stayed on, so I went to Auto Zone for a diagnosis. The fault code is P1077, and diagnosis is IMRC valve stuck short, Open or short circuit condition, failed IMRC actuator.

I've found very little info about this on the Internet. Is this something I should expect to be able to tackle myself, or do I need to submit to highway robbery at a dealer?

Thanks

Im not sure what that is or if you can do.it yourself. If you can't you don't necessarily need to go to the dealer. Go to a few small, privately owned shops (preferably one that specializes in Japanese cars) tell them what the problem is ask if they can fix it, and if so, what's the price.
