hello! I have a BMW F30 with an N20 engine and I have the following question:
is it advisable to leave the car from the spot, how long does it take to warm up on the first cold start?
for me, if I don't let it idle at 700 rpm, and I accelerate it while it's trying to warm up, it starts to drop at around 300 rpm or even stops!

could it be because I don't let it stabilize at 700rpm at the first cold start?
if I accelerate it when the engine is still at 800-850 rpm, the ratio drops to 300 rpm and the engine even stops

You don't need to wait for it to warm up. Just drive conservatively for 10-15 minutes.

no matter how I drive, the idle drops until the engine warms up 😡
