hey buddy, i own a 2.8 v6 spyder, and i sometimes have the same issue, we call it hunting, when the revs bounce up and down sometimes stalling.
well, this is normally a very simple case of 2 things,
1: air screw set too tight n not allowing correct revs
2: air screw covered in oil etc n giving engine ecu inncorrect mesurements of air flow=bouncing revs etc
cure, on the right of ur air plenum, u will see a red unit(plastic) which leads to a largeish brass screw, well, unsrew completely, and thouroughy wipe clean, usually covered in oil etc and then put back in, till about 2\3 mm left protruding, then start car and wait till choke cuts out and simply screw in or out to set idle speed
i hope thius solves your problem
