    S52 Idle issue, starts right up then dies 15 second later

    My 1991 s52 shuts off after runing 15 seconds.
    I finished installing Head gasket with arp bolts. It was idling fine for the test drive and thruout the bleeding session.

    Will not running the intake support mount cause a vac leak?

    i did the smoke test and it lead to tightening the valve cover gasket.
    I was adjusting the throttle cable its a 318is cable. Also adjusted the screw on the throttle body.

    mad sure icv good wires good

    hammered the dipstick down with the correct oring.

    the injectors were redone a bout 2 months ago there was a notice saying install injectors right away or something. Could this be the reason for the rough idle.

    Also i might have the fpr routed to the wrong vac line.

    Does the ground wire going to the dme mater cause ive been runing with out for a while in the process of rewiring 4 cut/crumbled wires going from the adapter one of the being the diagnostic wire.

    any advice, that may help.

        Update on idle issue.

        I realized that the car only starts up and stays running when i have the radiator cap open.
