Some things to consider, from my misfire article:
7) Injector function
At the harness connector, check for proper battery voltage at the power feed for the injector (pink for most modules). Check for pulse control with a noid light or test probe on all cylinders. Consider an injector balance test with a pulse box where you watch the pressure drop/fuel delivery of each injector. Look for less tan a 1.5 psi spread with a target around 3X psi. Consider measuring injector coil resistance and look for a target of 11-14 ohms with a range of less than 3 ohms across the injectors.

Had similar problems the misfire is not letting it burn all the fuel. The distributor is bad about wearing out on these I replaced it and fixed my misfire after a complete tuneup didn’t fix it
