Normal fuel pressure at idle but you must log at heavier load to see if fuel line issue. If you replaced plugs with the proper ones or upgraded ones and still have misfires then will be coils or fuel supply related. And I hope you're not running lower than 91-93 fuel.....

Proper heat range 8 or 9 plugs, aftermarket fuel line, and 91-93 fuel should fix it. New OEM coils may also be needed.

The older cars had much worse components and tunes in them and running lower octane fuel makes it even worse.

Oem coils are less than $200 shipped a set and can get them in less than a week.
