Fault code troubleshoot 2005 330ci

[Cpolite21]

I started my car this morning and got these codes. Can anyone help me figure out the source? It’s ran perfect since I’ve had the car( 6 months) except sometimes I have to start it numerous times in cold weather to get it going. It’s showing me codes:001593, p0123, p0301, and p1693

Can you check and repost the first one? I think there's a typo.

If it's a P1593, and a misfire, and a throttle position error, first get the engine smoke tested. It's most likely a vacuum leak. When unmetered air gets in it causes the computer to freak out because it doesn't understand why the mixture is lean, i.e. too much air, but the MAF says otherwise. Starting and dying in cold weather is a symptom of a vacuum leak, although that's not necessarily the only reason.

After you smoke it, report back. And get a better code scanner. INPA/ISTA if nothing else.

i appreciate your help, I’ll definitely get it checked for vacuum leaks. I used some cheap scanner to pull the codes but that is the code it gave me, it wasn’t a typo. Hopefully it is just a vacuum leak, that sounds like a pretty cheap fix. I’ll keep you updated when I’m able to get it checked out
