I would say if you’re positive you don’t have any fluid loss even in the combustion chamber, or in your oil. It could be the computer relearning the idle after having the battery unplugged or it can be a sensor in your distributor(I have a 93 prelude with h22) I had that problem but my idle was really erratic, check all vacuum lines, clean EGR valve or read this also THE END OF ALL Idle Surge - Bounce - etc Problems Thread - Honda-Tech - Honda Forum Discussion
