Hi, hoping someone can shed some knowledge before I go mad,just bought a 1978 5.7 caddilac seville. Been off road for a couple of years, changed a few bits etc, but it's got a problem that when you love it from park to drive/reverse the engine stalls. Works fine when the auto choke thing is on when it's cold, but as soon as it warms up it stalls when its moved to D. Once its moving it's fine, drives nice, changes gear etc, but when you come up to the lights it stalls. Tried increasing idle speed etc but made no difference. It seems ok when doing it from cold. Anyone got any ideas to try? Could old trans oil cause this.
