New update

Decidied to see if my ecu is showing codes

Currently have code 14 and 21

Code 14 is speed sensor issue which im aware of(speedometer doesnt work lol)

What caught my eye though was code 21 which is Ignition signal missing in primary coil

So i bought a new ignition coil and installed it

Once started up, it sounded like ass and now cylinder 3 is misfiring(pulled spark plug wire out and engine wasnt affected)

So i guess i still have misfiring issues

Welp, so i bought the rest of the injectors and fuel system cleaner to clean everything fuel related like the lines and stuff(Is this stuff worth it or dont use it? Its the techron brand)

a fuel filter is highly unlikely to be an issue
techron is good (all injector cleaners are)

check out the engine control and emmissions chapter in the s13 fsm I assume your sohc but the dohc electronics are pretty much identical in how they work
they have diagnostic procedures step by step very simple to work you through this.

I got a 21 and it ended up being my distributor though my symptoms were a little different
