Hey guys
Got a strange problem

My 96 vit. When I start her and she's cold the idle is quite low. Around 800 Rpm. This causes it to die or stutter. If I give it some revs its OK. Once I hit it into drive it sometime stalls and I have to start her and keep the revs up. Once I get moving its fine. If I stop and put into park the idle is about 1500.

It only does this when cold. Once it's warm I can start any time and it won't stall. I've replaced the thermostat and cleaned the throttle body. Am yet to change plugs and leads. Not sure if it sounds like plugs or vacume leak as its fine once its warmish. Anyone able to help diagnose.
Its an auto Efi.
Cheers
