engine seems underpowered

99 TJ (sport) i6 auto(5?) here, The engine seems unresponsive.

Could it be a spark plug problem?
I put new ones 3 months ago ( nhk cooper)

edit: seeing another thread I should mention the TJ came with 33' tires, d35c B, d30 F, I don't know the GR I would assume is stock.
