Idle problem after startup, 350 mag
Ive got an 87 with 350 mags
The port engine was stalling out IN gear when i idle around. I dont think its the shift interupt, because it happens after its in gear.
I turned up the idle (temporarily) and it still does it. It idles high, then when its in gear, i can be idling and it will die. New plugs/wires/cap/dist.
I ran a ton of b-12 through it.
Where should i start? vacuum leak or something sticking in the carb?
Its a pain in the a$$ around the docks with one engine dying

You need to check your IAC (Idle Air Control) settings. You need a scan tool or a volt metdr to do this. Pretty simple. For the "How to" do a search for "Setting IAC" or IAC. I wrote a procedure up on OSO about a year ago.
or use a Merc manual.
Good Luck.

I have the exact same problem engine runs great when cold but when it's warm and I come down to idle it stalls (intermittently), where's the best place to get a rebuild kit from?
