Toyota Repair/P1305, P1300 and more.. please help


ok so I have a 2002 Toyota celica gt and it recently just gave me problems on a road trip.. the check engine light started flashing.. so I took it in to get scanned and the codes that came up were. P1300, P1305, P0300, P0301, P0302..  I also looked at the relay and fuse box.. I noticed I had 2 empty spots.. one says EFI and the other one says C/OPN.. are those spots suppose to have a relay fuse? or are they meant to be empty?

The efi and the circuit opening relays should be there, if not I don't see how the engine would run at all since the fuel pump would not power up, at this time I'm not sure since the engine does run. As far as the codes got they mean there is a misfire on cyliners #1 and #2, the ignition coils (one on each spark plug) are a common source for this type of misfire, if you feel the spark plugs are not the problem and have already been replaced then try replacing both of these coil packs, they are available aftermarket at most autoparts stores a lot cheaper than the OEM.
