4th gen h22 swap hesitation

Well, a while back i swapped the h22 into my prelude, and it seems that every once in a while (doesnt seem to occur at the same time, its like random) between 2-3k rpm it like hesitates, feels like its just loses a little power, then goes right back to normal. It didnt do it with the h23 Im not sure what it could be, ive heard of it being maybe a map sensor, or knock sensor. My check engine light isnt on either. If anyone has a similar problem please let me know, any info will help. Thanks guys.

start unplugging a sensor at a time to see if the situation stays the same - if it does - replace that sensor.

which sensors do you think i should start trying first. which ones might cause the problems
