OK, so it's not the gas cap, I replaced that with a new OEM cap. What do I look for next?

Your profile shows you have a '90 Miata and a P0455 isn't even on the list of possible codes for that car.
If I were you I'd sell it quick!::Drive2::
Got that on my '99. Turned out to be a vacuum hose on the bottom/front of the intake manifold, just past the throttle body had popped off. I put it back on, no more CEL. It went to the canister in the front.
Profile updated.
I've got that code on my 99 right now as well. I'll be checking the vacuum lines this weekend.
No bad vacuum lines. What next, vacuum canister?
