Why does my Mazda 6 engine hesitate under acceleration?
If the idle issue only happens when it’s cold outside your car is just doing a cold start which is normal. As for the hesitation under acceleration, the first suggestions I have would be the ignition system (spark plugs, coils, wires), fuel pump, or fuel filter. Yeah I’m in Massachusetts so it’s getting to be below freezing at this time of year.

Why does my Mazda 3 idle with no AC?
After driving a bit and the engine warming up completely, whenever i stop the idle drops down to ~400-500 rpms and feels/sounds rough, no AC on. But it has never died on me, never thrown any lights or codes, and runs like a champ when you’re actually driving and idle improves when in park or neutral.
Why does my Mazda 3 want to stall?
I’ve got the EXACT same problem. Put it in Neutral or Park, idles at 700 RPM. Put it in Drive and brake, idles at 300 and it feels like the car wants to stall. When the car is cold, it’s fine. When it warms up, it acts up.

Rough idle, bad hesitation… This problem started suddenly. Very rough idle with a repetitive cycle that is smooth for a couple of seconds then misses badly, occasionally stalling. Worse problem is bad hesitation when accelerating after throttle at idle position, sometimes stalling.
What’s the worst idle time in a car?
Worst after stationary idle, but also after moving at low to medium speed with closed throttle and then accelerating. Also very hard to start because of periodic ‘backfire’ while cranking that brings engine to standstill.
