P0304 Code indicates a misfire on cylinder 4
Most likely causes for this are bad wire, bad spark plug, bad coil(s) or bad dist cap if so equiped.
A vacuum leak can also cause a misfire.
Seeing the vehicle is going on 13 years old replacing the wires and the plugs would be a good place to start, and could be the solution

2003 acura tl error codes po301 po302 po304 po306 p1399 po300

PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

PO304--- Possible Bad Ignition Coil on cylinder #4

PO136-- O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)

Could be sensor or wiring or misfire or other items

You should have changed the front or upstream O2 sensors
on all your vehicles at 100,000 miles

The coil code may or may not be correct
You have to diagnose cylinder misfires

I would suggest a repair shop & they have to use a scan tool
in Mode #06 on a road trip of at least 20 miles, to check for
cylinder misfire counts or use an oscilloscope on a road test

If replacing the coil on #4 resolves the issue, it was just luck,
& luck only goes so far

I had a coil in June that no professional test equip found
I had to walk a new one one cyl at a time
