Terri​​​​​​ble idle. Drove it one day just fine it sat for a couple of days then it just started doing this. Smokes really bad. Checked plugs pretty sure they're fouled because they are straight up black lol.

sounds like way too much fuel, so either the return line to the tank got plugged somehow, your injectors are sticking open or your AFM flapper is stuck open.

i got an S5 AFM on the floor next to me that is stuck open, so i'd probably start by checking that, because it can happen.
