Looking for help on a 1997 Honda Accord 2.2L non v-Tec. The car has very high miles (340,000) it has a new head timing belt etc. Car has slight stumble/ hesitation under reasonable throttle at around 2000-2500rpm. If I put the throttle to the floor through the gears the hesitation is not there. I’ve run tests and changed all the usual components. The car seems to be running rich with a STFT of -11.0 to -14.0 at idol and -27.3 at 2500rpm I have more results for tests I can add to help I’m just looking for any ideas on how to make the hesitation go away thank you.

Things I’ve done-

​​​​​​—Plugs
—Wires
— cap&rotor
—oil change & new filter
— new fuel filter
—fuel pressure test was around 35psi
—ignition coil checked out

ill post my scanner test results below here
