Misfire - only at start-up Hey guys,
Have a misfire, only for the first 2/3 minutes after starting the car. Funny enough, its everytime I start the car, not just when its cold.
I can drive it for a bit. Turn it off and back on and it will mis again until I start driving.
Just started last week.
Any help is appreciated.

Could be a head gasket or leaky injector. Coolant, or gas, drips into the cylinder while the motor sits and causes a miss until it burns it off. Very common symptom.
a leaking injector would also cause a long crank as well, if that helps aid in diagnosis. You can pull the plugs and check for a fuel fouled plug. Should smell like fuel or be very black
When you shut it off/ and restart warm is it still for 2/3 minutes ?
Trying to figure if it goes away once it goes into closed loop
