    P1312 and P1334 error codes

    I have intermittent P1312 and P1334 error codes, usually after journeys on highways, around town never get them.
    My research points to P1312 as misfire cylinders 1&2 and P1334 as misfire cylinders 3&4
    I've changed the plugs for NGK BCPR6ES-11 and inspected the DIC for damage which appears to be ok however was planning to change the DIC.
    Before I do and spend 230 is their any other faults that would bring these error codes on the CEL

    99.9% chance you'll need a new DIC as these are the typical codes for one that's failing.

    Had the same problem recently. Changed plugs, still came up. So I replaced the DIC as Wulf suggested. Bought this one: More Information for AIRTEX / WELLS 5C1762

    It's the OEM SEM unit. Looks like GBP 95 before shipping/brokerage. It was worth it for me in Canada. You may want to check it out.

    Bought Saab OEM DIC from EuroCarparts cost 275 - Can confirm it's original Saab, part number 55559955
    Monitored for error codes over the last week and non have appeared when they typically would have so problem solved.
    Old DIC did not show any signs of burning and no cracks were evident........
