Default 95 acura integra. cleaned injectors, now have less power?

Did a before spray test on each injector and noticed no cone spray pattern or atomization of fluid. Volume was evenly matched for each injector. Did an ultrasonic cleaning twice for 10 minutes. Observed flow rate and pattern at 650 rpm to 6500rpms. Very good cone shape and atomization. Installed injectors back on car. Performed a road test. Idle was very smooth but takes more effort when floored to reach speed and accelerate. Somewhat of a lag for it to kick in. Engine is a 2.0 b20b used engine @ 30k miles. Very good power before injector cleaning. but noticed less power after cleaning. What can this be?

Are the spark plugs very worn? The plugs may have been good enough when the injectors weren't supplying the correct amount of fuel, but now may be too worn to provide good spark for the proper amount of fuel.
