Default Low (below 2k) RPM mis-fire/hesitation issue

Just got another Yata. 1992 1.6L. I have found that if I am in 2nd or 3rd and let off the gas and then let the RPM's drop to below 2k then hit the gas hard the car misfires and stumbles for a second or two then picks back up and acts like nothing was wrong. If I slowly get back on the gas and not just punch it the problem doesnt happen but you need to slowly give it gas. Problem doesnt happen in high RPM (any gear or any speed even to redline the problem doesnt happen) or if you punch the gas say at 2200 RPM only when it dips below 2k.

I was thinking maybe Spark Plugs or Wires but also thinking FPR or Filter?

Anyone have other ideas or thoughts?
