Miss when accelerating from lower RPM.

Hello everybody, I’ve got a 98 Tacoma that I use for hunting. Lately it’s developed a quick misfire when accelerating from lower RPM’s.
It’s a really quick kinda jump in the engine, usually when easing up from 2nd gear, sometimes 1st.
It got newer plugs and wires, 2 years ago- maybe 15-20k miles. It runs perfectly otherwise, just the low rpm deal, around 1200 I think.

It’s not throwing a code. What else would cause this?

Thank you all very much!!
