Hitting a wall here trying to figure this shit out. Every time the car starts cold (even if it's a warm day) It idles like ass and wants to die out until it warms up. Goes away within about a minute of feathering the throttle then runs perfect. When you touch the throttle it dies off then revs up a bit when released. Started doing this a few months ago, got worse and has stayed how it is for a bit now. So far I've checked:
Resistance checked Coils and plug wires
Replaced plugs with BKR6EKPB11, runs better but didn't help starting.
Only fault code that isn't auto trans related is Power steering pressure sensor.
EDIT: Forgot to mention car is dumping white unburnt fuel smoke.
