    I’m thinking more ecu as it disappears after restarting. Poss need remapping.

    As injectors run by ecu and if fault on rail all would be throwing up fault.

    Have you just bought the car? I know someone got rid of theirs due to a bad remap, it never ran right after and was "locked" apparently.

    What I would do is check all pipe work is secured
    More so on the secondary air circulation
    Then switch all plugs and coil packs from front to rear if symptoms persist and codes remain the same I'd say your looking at something more serious
