Start-up Idle Issue

Have a 2004 330CI ZHP. When I start the car, the starter usually runs a little longer than usual, then the engine is super low on RPMs and running rough. There is a blackish smoke coming out of the tail pipe. This will go on for ever as far as I know, until I push on the gas once, then it idles perfectly, runs smooth and otherwise the car operates well. Check engine light never turns on, so the dealer says they do not know what is wrong.

Dealer says, go get gas at a different station. I have, nothing has changed.

Dealer says said put in fuel system cleaner. After that, it reduces how often it happens, but does not eliminate it and once the cleaner is out of the tank, the issue comes back.

Wanted to ask for advice before I go out and get more fuel system cleaner as it is the only thing that helps.

Thank you all.

(I put in 93 octane)
