Default Car shake after spark plug replace, normal?

So I change my spark plug today by myself following the DIY here
I replace with the NGK xxxxx-11S (the OEM one)
https://www.s2ki.com/forums/index.php?showt...&#entry13340095
After I change it, I started the car.
Car usually idle at 1600rpm and drop to 800rpm for my AP1.
This time it start at 1400rpm, and fall to 1000rpm, 900rpm, and 800rpm, within 5seconds.
And car is shaking too.
So I shot it off before it fall under 750rpm.

Is it normal? or should I let it run for a couple mins?

No. Not normal. Check your handiwork again. You may not have secured all the connections on the coilpack plugs properly.
