Stalled when oil filler cap off.

[rob hod]

    IME on NA cars It also varies according to which type of breathing your
car has. The ones with the big collapso rubber type 44 with a big steel tube
into the intake boot will stall , or nearly stall. The older  80/CGT
arrangement is different and on a well tuned car (de moi of course) it
merely dips and struggles a bit

    YMMV.
