Misfiring during deceleration (Brop brop brop brop brop)

[MezaS13]

I have a 91 240SX KA24DE that misfires like crazy when I decelerate as soon as I let go off the gas, when the RPMs drop some 300 revs it starts with the brop brop brop brop brop brop brop brop brop until it reaches 2000 where I either leave it in neutral or downshift to brake.

probably your 02 sensor time for a new one

It is your 02 sensor. The same thing happened to my 95 (auto) but it was a nice little show for everyone else lol. Turns out, mine was just unplugged lol (the previous owner caused a lot of problems that i have to fix because he's a bone head lol).
