Replaced Motor and ECS - Flies perfectly in acro but not in stabilized modes

[tekgecko]

I replaced a broken motor and ESC of my quad (slightly different to the others I have on there but the same spec)

When flying in acro mode it works perfectly, but if I switch to any mode that has auto leveling on it starts to wobble until it becomes unstable and crashes.

Does anyone know why this may be?

Sound like a bad gyro to me. This begs the question: why use an auto level mode at all?

That's what I feared, the Gyro is in the FC so that would need replacing. I am quite new to acro mode still so like the option to switch back to a more stable flight mode

My advice: stop using stable all together. It teaches bad habits. Fly within your ability, but right at the edge. Every time you save your craft by putting in stable you've missed a chance at learning how to correct.

When I teach people how to fly, I give them a max of 3-5 packs on stable, then they get thrown in the deep end

Okay fair play will give it a go

I forgot to ask you what version of Betaflight you're running, and do you know what your pid loop is running at? If you have a really slow PID loop, your low pass filters might be causing interference. This would be a very uncommon scenario, but it's possible. (I think)
I have to say I'm not an expert here. Here's a link if you're curious

Looptime and Flight Controller - Oscar Liang

This article explains what FC looptime is and how faster looptime might affect your quadcopter's flight performance. We'll also talk about gyro update frequency and ESC refresh rate which are equally important.
