Good evening! Ok...I have this messed up issue happening lately in the mornings when I first start my car.....
When I go to start it....it starts on a dime...but almost stalls....takes about 2 seconds to find itself....then will be fine for the day.
The temp here is around 4c....but even on days when it was -10c it would start fine.
No check engine light on...below is a list of things I have had done in the past month or 2...

Imt O Rings
Inlet Gaskets or seals...
New Plugs
replaced #2 bank 2 sensor
replaced mass air flow sensor
replaced #1 sensor on bank 2
new coolant tank and coolant..
new heated winshield

Thank you for the help as always!!

 

How old is the battery? A failing one will usually start the car but the voltages and peak currents at top voltage drop.

I suppose another possibility would be a small air leak which seals as the car warms.

There are other (generally hard to figure out) things it might be, like a "lazy" (improperly working) sensor.

It's tough for it to set most codes at start up as it's not got stable enough readings.

You might check the (long term) fuel trims in case they point to (or away from) a leak. You'd need an OBD tool (& laptop preferably) that can do live data - such as a USB elm327, very cheap indeed.
